20 foot ladder leans against the building and reaches a point 13 feet above the ground find to the nearest degree the angle that ladder makes with the ground
.
Since it forms a "right triangle" we can apply trigonometry.
sin x = oppo/hyp
sin x = 13/20
x = sin^-1(13/20)
x = sin^-1(0.65)
x = 40.5
rounded to nearest degree
x = 41 degrees
