Use the diagram to find the value of x to the nearest tenth of a foot. a. 74.6 ft.
b. 5.3 ft.
c. 15.5 ft.
d. 73.3 ft.

a

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan15° = = ( multiply both sides by x )

x × tan15° = 20 ( divide both sides by tan15° )

x = ≈ 74.6 ft ( to the nearest tenth of a foot )

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
