Angle 1 and Angle 2 are complementary angles. The measure of Angle 1 is 66 degrees. The measure of Angle 2 is 2x degrees. Find the value of x.
Answer:
Step-by-step explanation:
Complementary angles add up to 90°
∠1 + ∠2 = 90°
66 + 2x = 90°
2x = 90° - 66°
2x = 24°
x = 24/2
x = 12°
∠2 = 2*12
∠2 = 24°
Plot the points A(7,1), B(-2, 3), C(1, -7) on the coordinate axes below. State the
coordinates of point D such that A, B, C, and D would form a parallelogram.
(Plotting point D is optional.)
A B
D C
vectors
AB = DC
AB (-2-7 ; 3-1) => AB (-9 ; 2)
DC (1-x : -7-y)
1 - x = -9 => x = 10
-7-y = 2 => y = -9
D(10 ; -9)
Answer:
D = (10, -9)
Step-by-step explanation:
If ABCD is a parallelogram, then AB = DC and BC = AD
Therefore,
[tex]\sf x_A-x_B=x_D-x_C[/tex]
[tex]\sf \implies 7-(-2)=x_D-1[/tex]
[tex]\sf \implies x_D=10[/tex]
[tex]\sf y_A-y_B=y_D-y_C[/tex]
[tex]\sf \implies 1-3=y_D-(-7)[/tex]
[tex]\sf \implies y_D=-9[/tex]
Therefore, D = (10, -9)
use the diagram to find the distance across the suspension bridge. Round your answer to the nearest foot
Applying the tangent ratio, the distance across the suspension bridge is: 499.2 ft.
What is the Tangent Ratio?Where we are given a right triangle, the tangent ratio is determined using the formula, tan ∅ = opposite side/adjacent side.
The diagram atatched beow whos the distance across the suspension bridge which consists of 6 identical right triangles.
Find the adjacent side of each right triangle using the tangent ratio:
∅ = 32
Opposite side = 52 ft
Adjacent side = x
Plug in the values into the tangent ratio:
tan 32 = 52/x
x = 52/tan 32
x = 83.2 ft.
Distance across the suspension bridge = 6(83.2) = 499.2 ft.
Therefore, applying the tangent ratio, the distance across the suspension bridge is: 499.2 ft.

Use the figure to answer the question.
What is the area of the triangle on the left?
Answer: 15
Step-by-step explanation:
Area of a triangle = base * height.
Since the inside figure is a square, the base of the triangle must be 5.
To find the height: The length of the entire figure is 17; subtract 5 to account for the square, and you know that the remaining 12 must be divided easily on the right and left side; this shows that the height of the triangle on the left must be 6.
Plug these numbers into the formula: 5 * 6 / 2 = 15 :)
Answer:
the answer is 29
Step-by-step explanation:
The answer is 12 because
the length is 17 then i did minus 5 since that's the width
17-5=12
that's the length for the slanted part then......
12+12=24+5=29
(you get 5 from if you see the straight line on the right is 5 so on the other its the same thing.

Find the 8th term of the sequence whose common ratio is 1/3 and whose first term is 3
Answer:
The 8th term is [tex]\frac{1}{729}[/tex].
Step-by-step explanation:
Let's begin with the formula for a geometric sequence. We know this is geometric because we are working with a common ratio, or the number we multiply to find each term.
[tex]a_n=a_0(r)^{n-1}[/tex]
In this formula, [tex]a_0[/tex] is the first term, [tex]r[/tex] is the common ratio, and [tex]n[/tex] is the desired term. We know the values of [tex]r[/tex], [tex]a_0[/tex], and [tex]n[/tex] from the given information:
[tex]a_0=3\\r=\frac{1}{3}\\n=8[/tex]
Substituting those values we get:
[tex]a_8=3(\frac{1}{3})^{8-1}[/tex]
[tex]a_8=3(\frac{1}{3})^7\\a_8=3(\frac{1}{2187})\\a_8=\frac{3}{2187}\\a_8=\frac{1}{729}[/tex]

A plane takes off from an airport at an angle of 14.5°. If the plane is traveling at a velocity of 220 feet per second, how high off of the ground is the plane at 10 seconds?
The distance of the plane travelling at 220 feet per second off the ground is 151.71feet
How to calculate the maximum height of an objectMaximum height of the plane is expressed as:
[tex]M=\frac{u^2sin^2\theta}{2g}[/tex]
u is the velocity = 220ft/s
θ is the angle of elevation = 14.5°.
g is the acceleration due to gravity
Substitute

How much of a radioactive substance must be presented to decay to 80 grams in 12 years if the half-life of the substance is 7.6 years?
Answer:
Radioactive in half life is 51gram
Step-by-step explanation:
80grams:12years
X :7.6years
12x÷x=x
7.6×80÷12=51gram
Answer:
239 grams.
Step-by-step explanation:
Half life t(1/2) = ln 2 / k
So 7.6 = ln 2 / k
k = ln 2 / 7.6 = 0 0901204
N = No e^-kt
So after 12 years
80 = No / e^(-0.0901204*12)
No = 80 / e^(-0.0901204*12)
