Hello, Joker37!
Did you make a sketch?
To calculate the height of a crane which is on top of a building,
Denis measures the angle of elevation to the bottom and top of the crane.
These were 62° and 68° respectively.
If the building is 42 m high find, to 2 decimal places:
a) how far Denis is from the building
b) the height of the crane. Code:
A o

The crane is
The building is
Denis is at
(a) In right triangle ft.
(b) In right triangle ft.
Edit: Too slow again . . . *sigh*
