The length of the hypotenuse, line segment ac, in right triangle abc is 25 cm. the length of line segment bc is 15 cm. which is the approximate measure of angle acb? 31.0° 36.9° 53.1° 59.0°

The answer is 53.1 degrees.You would draw and label a triangle. When you do this you see that you are looking for the angle between the adjacent and hypotenuse. You would use the trig function cosine to solve. Since we need an angle, we use cos^-1.cos-1(15/25) = 53.1 degrees
