Line segment SU is a diameter of circle V.
What is the measure of arc S T?
56°
68°
112°
163° (it is 56!)
Answer:
Answer: 112°
Step-by-step explanation:
Angles in a Circle
An inscribed angle is formed between two chords whose vertices lie on the circumference of a circle. The figure shows three chords: TU, SU, and ST. SU happens to also be a diameter because it goes through the center of the circle V.
ST and SU form an inscribed angle of 34°. The corresponding central angle is TVU and its measure is
[tex]m\angle TVU=2*34^\circ=68^\circ[/tex]
The required measure of the arc ST is the measure of the angle SVT. Note that SVT and TVU are complementary, thus:
[tex]m\angle TVU+m\angle SVT=180^\circ[/tex]
Solving for the measure of SVT:
[tex]m\angle SVT=180^\circ-m\angle TVU[/tex]
[tex]m\angle SVT=180^\circ-68^\circ=112^\circ[/tex]

If G is the incenter of triangle ABC, find each measure
Answer:
m∠ABG = 20 degrees
m∠BCA = 22 degrees
m∠BAC = 118 degrees
m∠BAG = 59 degrees
DG = 4
BE = 12.4
BG = 11.7
GC = 20.4
Step-by-step explanation:
The given parameters are;
m∠CBG = 20°, m∠BCG = 11°
The incenter of a triangle is the point where the three bisectors of ΔABC meets
m∠ABG = m∠CBG = 20° by definition of angle bisector
m∠ABG = 20°
m∠ACG = m∠BCG = 11° by definition of angle bisector
m∠BCA = m∠ACG + m∠BCG = 11° + 11° = 22°
m∠ABC = m∠ABG + m∠CBG = 20° + 20° = 40°
m∠BAC = 180° - (m∠BCA+m∠ABC) = 180° - (40° + 22°) = 118°
m∠BAG = m∠CAG by definition of angle bisector
m∠BAC = 118° = m∠BAG + m∠CAG = m∠BAG + m∠BAG = 2 × m∠BAG
2 × mBAG = 118°
m∠BAG = 118°/2 = 59°
m∠BAG = 59°
Given that "G" is the incenter of the triangle ABC, we have;
GF = GE = DG = The radius of the incircle of the triangle = 4
Therefore, by Pythagoras' theorem, we have;
BG = √(11² + 4²) = √137 ≈ 11.7
BE = √((BG)² + 4²) = √(137 + 4²) = √153 ≈ 12.4
GC = √(20² + 4²) = √416= 4·√26 ≈ 20.4
Applying the definition of the incenter of a triangle, the measures in triangle ABC where G is the incenter are:
[tex]\mathbf{m \angle ABG = 20^{\circ}}[/tex][tex]\mathbf{m \angle BCA = 22^{\circ}}[/tex][tex]\mathbf{m \angle BAC = 118^{\circ}}[/tex][tex]\mathbf{m \angle BAG = 59^{\circ}}[/tex]DG = 4BE = 10.99BG = 11.7GC = 20.4Recall the following facts about the incenter of a triangle:
The incenter of a triangle is the point where the three angle bisectors that divides each angle vertex into two intersect each other.
The incenter also, is a point equidistant to all three sides of the triangle at right angle.
Applying the properties above, the measures in the image can be calculated as shown below.
Given:
[tex]m \angle EBG = 20^{\circ}\\\\m \angle ECG = 11^{\circ}\\\\CF = 20\\\\EG = 4\\\\BD = 11[/tex]
Find [tex]m \angle ABG[/tex]:
[tex]m \angle ABG = m \angle EBG[/tex] (angle bisector definition)
Substitute[tex]\mathbf{m \angle ABG = 20^{\circ}}[/tex]
Find [tex]m \angle BCA[/tex]:
[tex]m \angle BCA = 2(m \angle ECG)[/tex] (angle bisector definition)
Substitute[tex]m \angle BCA = 2(11)\\\\\mathbf{m \angle BCA = 22^{\circ}}[/tex]
Find [tex]m \angle BAC[/tex]:
[tex]m \angle BAC = 180 - (m \angle CBA + m \angle BCA)[/tex] (sum of triangle definition)
Substitute[tex]m \angle BAC = 180 - (40 + 22)\\\\\mathbf{m \angle BAC = 118^{\circ}}[/tex]
Find [tex]m \angle BAG[/tex]:
[tex]m \angle BAG = \frac{1}{2} (m \angle BAC)[/tex] (angle bisector definition)
Substitute[tex]m \angle BAG = \frac{1}{2} (118)\\\\\mathbf{m \angle BAG = 59^{\circ}}[/tex]
Find DG:
[tex]DG = EG[/tex] (Perpendicular bisectors of the sides of a the triangle are equal in length from the incenter of a triangle)
Substitute[tex]\mathbf{DG = 4}[/tex]
Find BG:
[tex]BG = \sqrt{BD^2 + DG^2}[/tex] (Pythagorean Theorem)
Substitute[tex]BG = \sqrt{11^2 + 4^2} \\\\BG = \sqrt{137} \\\\\mathbf{BG = 11.7}[/tex]
Find BE:
[tex]BE = \sqrt{BG^2 - EG^2}[/tex] (Pythagorean Theorem)
Substitute[tex]BE = \sqrt{11.7^2 - 4^2} \\\\BE = \sqrt{120.89} \\\\\mathbf{BE = 10.99}[/tex]
Find GC:
[tex]GC = \sqrt{CF^2 + FG^2}[/tex] (Pythagorean Theorem)
Substitute[tex]GC = \sqrt{20^2 + 4^2} \\\\GC = \sqrt{416} \\\\\mathbf{GC = 20.4}[/tex]
In summary, applying the definition of the incenter of a triangle, the measures in triangle ABC where G is the incenter are:
[tex]\mathbf{m \angle ABG = 20^{\circ}}[/tex][tex]\mathbf{m \angle BCA = 22^{\circ}}[/tex][tex]\mathbf{m \angle BAC = 118^{\circ}}[/tex][tex]\mathbf{m \angle BAG = 59^{\circ}}[/tex]DG = 4BE = 10.99BG = 11.7GC = 20.4Learn more here:

A motorboat travels Downstream on a river for 5 hours. The speed of the current is 2 km/h. The river flows into a still Lake and the motorboat continues for two more hours. The distance covered by the boat on the river was 40 km more than the distance that was covered on the lake. What is the speed of the motorboat in still water?
Answer:
I think it is 10 km/hr
Step-by-step explanation:
5 hrs = 40 more with 2 km/hr current
2 hrs= less 40 no current
40-2x5=30
30 without current for three hours
30/3=10 km/hr no current
CHECK
10x2=20
10x5=50+2x5=60
The speed of the motorboat in still water is 10 km/hr
A motorboat travels downstream on a river for 5 hours.
The speed of the current = 2 km/h
The river flows into a still lake and the motorboat continues for two more hours.
The distance covered by the boat on the river was 40 km more than the distance that was covered on the lake.
We have to determine the speed of the motorboat in still water
Let the speed of motorboat in still water = m km/h
Given that
The speed of river current = 2 km/hr
The river runs into a still lake
The motorboat continues to travel for 2 more hours
The distance traveled by the motorboat in two more hours in the lake = 2m km
The distance covered by the boat in the river = (40 +2m) km
Net speed of the boat in the river = (m +2 ) km/hr
Let t be the time spent by motorboat into the river.
[tex]\rm Time = \dfrac{Distance}{Speed}[/tex]
[tex]\rm t = \dfrac{40+2m }{m +2}..........(1)[/tex]
Given that the motorboat travels downstream of the river for 5 hrs
so on putting t = 5 in equation (1).
[tex]\rm 5 = \dfrac{40 +2m }{m+2}\\\\5m +10 = 40 +2m\\5m -2m = 40-10\\3m = 30\\m = 10 km/h[/tex]
So the speed of the motorboat in still water is 10 km/hr

In the following figure, m || QR. Then, the measure of ∠QPR is
Given:
m || QR
To find:
The measure of ∠QPR.
Solution:
Since m || QR and a transversal line intersect them, therefore the alternate interior angles are equal.
Let points S and T lie on the line m. S is on the right and T is on the left side of point P.
[tex]m\angle RPS=m\angle PRQ[/tex]
[tex]m\angle RPS=45^\circ[/tex]
Now, angles TPQ, QPR and RPS lie on the one side of a straight line. It means, their sum is 180 degrees.
[tex]m\angle TPQ+m\angle QPR+m\angle RPS=180^\circ[/tex]
[tex]50^\circ+m\angle QPR+45^\circ=180^\circ[/tex]
[tex]m\angle QPR+95^\circ=180^\circ[/tex]
[tex]m\angle QPR=180^\circ-95^\circ[/tex]
[tex]m\angle QPR=85^\circ[/tex]
Therefore, the measure of angle QPR is 85 degrees.

The total amount of income Xander earns from selling y books algebraically is C = 25000 + xy + 0.08y.
What is an equation?An equation is the statement that illustrates the variables given. In this case, two or more components are taken into consideration to describe the scenarios.
In this situation, Xander writes math textbooks that sell x dollars each, he received a bonus of $25,000 for signing a contract, and he receives 8% commission on each book sale.
c = total amount
y = number of books.
The total amount of income will be:
= 25000 + (x × y) + (8% × y)
= 25000 + xy + (0.08 × y)
C = 25000 + xy + 0.08y
