 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? Answer by jim_thompson5910(28536)   (Show Source): You can put this solution on YOUR website!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.
