Question 588748: If the hypotenuse of a right triangle is 10 inches, and an adjacent side is 5 inches, what is the measure of the angle between those two sides?

cos(theta) = adjacent/hypotenuse

cos(x) = 5/10

arccos(cos(x)) = arccos(5/10)

x = arccos(5/10)

x = arccos(0.5)

x = 60

So the measure of the angle is theta = 60 degrees.
