+31 Please answer the following. Please show work for the second question if you don't mind. Thank you!!!
for the second one, problem 3,
the ladder is the hypotenuse forming a right triangle with the wall and ground.
so for part a, sin is used.
sin angle = 9.2/10
use a calculator to solve that with arcsin or sin-1
for part b, cos is used.
cos 75 = x/10
x= 10 cos 75
x being the ground distance
