Answer:
D
Step-by-step explanation:
Took the test
<span>D) 322.75 feet
use the trigonometric ratio Tangent to solve for this problem.
Tan = Tan(angle) = opposite side / adjacent side
we dont know height of pole so use x for opposite side.
plug in values
tan(67) = x/137
multiply both sides by 137
137*tan(67) = x
plug into calculator to get 322.75</span>
3(r-16)=9
3r-48=9
3r=57
r=19
Let's solve for x first,
3x + 5y - 5y = 1 - 5y
3x/3 = 1/3 - 5y/3
x = 1/3 - 5/3y
Let's now plug that into the other equation,
7(1/3 - 5/3y) + 4y = -13
7/3 - 35/3y + 4y = -13
7/3 - 7 2/3y - 7/3 = -13 - 7/3
- 7 2/3y (-3/23) = -15 1/3 (-3/23)
y = 2
The answer is 2
