| The height AM of triangle ABC divides its side BC into segments BM and MC. Find the segment MC if AB = 10√2 cm, AC = 26 cm, ∠B = 45 °.
Consider the triangle ABM: angle M = 90 degrees (because AM is height), AB = 10√2, angle B = 45 degrees => BM = AM = x, according to the Pythagorean theorem we find AM: 100 * 2 = 2x ^ 2, x = 10. Consider the triangle AMC: angle M = 90 degrees, AM = 10, AC = 26, according to the Pythagorean theorem we find MS: 100 + MS ^ 2 = 676, MS = 24
