Two hills are 2 miles apart. the taller hill is 2707 ft high. the angle of depression from the top of the taller hill to the top of the shorter hill is 7 degrees. find the height of the shorter hill to the nearest foot. (remember: 1 mile = 5280 feet)

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.
