Answer 1

you have a right triangle with one leg 30 m (horizontal) and the other leg 50 m (vertical)

you don't need to find the hypotenuse

use the tangent function

tan=opposite/adjacent

tan(x)=50/30

tan(x)=1.6666....

use the arctan function on your calculator or use a table of values...

tangent of 59.03624347º=1.6666..., so therefore...

the answer is 59º B)
