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
