HELP please with this bizarre math problem:

"Mr. Diego" used a theodolite to map a region of land for his class in geomorhphology. To determine the elevation of a vertical rock formation, he measured the distance from the base of the formation to his position and the angle between the ground and the line of sight to the top of the formation. The distance was 43 meters and the angle was 36 degrees (triangle). What is the height of the formation to the nearest meter?

Thank you!

Just trig. Use tan(36)=(x/43) and solve for x.

It's just simple trig. The angle of elevation is 36 degrees. The leg adjacent to that angle is 43 m. Thus, you gotta employ tangent...

Tan x = opp leg/adj. leg

So, Tan (36)=h/43...etc.
