Aladder is placed 30 inches from a wall. it touches the wall at a height of 50 inches from the ground.
the angle made by the ladder with the ground degrees, and the length of the ladder inches

To find the length of the ladder, you need to do Pythagorean theorem.
50^2 + 30^2 = x^2
2500 + 900 = x^2
x^2 =3400
x= square root of 3400
58.31 OR 10 root34

To find the angle:
tan theta = opposite/adjacent
50/30 = 5/3
theta = tan inverse of 5/3
= 59.04
