In a right-angled triangle CDE with a right angle C, the leg CD is 10 cm, and its projection onto the hypotenuse is 8 cm. Find the second leg and the hypotenuse of the triangles.
The square of the leg is equal to the product of the hypotenuse and the projection of this leg to the hypotenuse, therefore
the hypotenuse is 10 ^ 2: 8 = 100: 8 = 12.5 cm
