Answer:
3/5
Step-by-step explanation:
We can find ∅ by using the tangent function since we have the opposite and adjacent sides of ∅.
tan(∅)=1/2
tan^-1(tan(∅))=tan^-1(1/2)
∅=26.57
Since we are looking for cos(2∅), then we have cos(2(26.57))=cos(53.14)≈0.6
So the exact value is 3/5

Answer:
x = 63
Step-by-step explanation:
a triangle is always 180 degrees, so you equation would be:
180 - 42 - 43 - 32 = x
180 - 42 - 43 - 32 = 63
so x = 63
Answer:
Step-by-step explanation:
a straight line = 180 degrees
on the right side, where the angle is 32 it is vertically opposite to the right angle of the triangle then

So you can subtract all the given angles you have (90 degrees and 42.7 degrees) from 180.

Hey there!
The answer is 6:54
The time on the clock shows 6:20, because the hour hand is after the 6, and the minute hand is on the 4 (which we multiply by 5 to get the minutes).
If it takes her 8 minutes to walk to the bus, 10 to pack lunch, and 16 to get dressed, that's a total of 8 + 10 + 16 minutes, or 34 minutes.
So, we add that to the minutes, so 20 + 34 = 54, therefore the time is 6:54 when she arrives.

What is the answer for m/1 =
Answers
=============================================================
Explanation:
The quickest way to get this answer is to add the angles given to get 87+46 = 133
This is through the use of the remote interior angle theorem.
Note how the angles 87 and 46 are interior, or inside the triangle. And also, they are not adjacent to the exterior angle we want to find. So that's where the "remote" portion comes in.
----------------
The slightly longer method involves letting x be the measure of the missing interior angle of the triangle.
The three interior angles add to 180
87+46+x = 180
133+x = 180
x = 180 - 133
x = 47
The missing interior angle of the triangle is 47 degrees.
Angle 1 is adjacent and supplementary to this 47 degree angle, so,
(angle1)+(47) = 180
angle1 = 180-47
angle1 = 133 degrees
This example helps confirm that the remote interior angle theorem is correct.

What is m∠A and what is m∠B?
Answers
Answer:
m∠A = 79°m∠B = 112°Step-by-step explanation:
We have cyclic quadrilateral as all vertexes are on the circle.
As per property of cyclic quadrilateral, each pair of opposite angles are supplementary.
As we know supplementary angles add up to 180°.
m∠A + m∠C = 180° ⇒ m∠A = 180° - 101° = 79°m∠B + m∠D = 180° ⇒m∠B = 180° - 68° = 112°factor 54-12 with GCF
