Question

Please help me out please ..

Answer 1

Answer:

x = 466.7 ft

Step-by-step explanation:

The lower angle in the right triangle = 31° ( alternate angle )

Using the cosine ratio in the right triangle, with hypotenuse x

cos31° = $\frac{adjacent}{hypotenuse}$ = $\frac{400}{x}$

Multiply both sides by x

x × cos31° = 400 ( divide both sides by cos31° )

x = $\frac{400}{cos31}$ ≈ 466.7

Answer 2

Step-by-step explanation:

tan 31=y/400

.6= y/400

y=240

x=((400)^2+(240)^2)^1/2

=466.65
