In a right-angled triangle ABC, the angle is C = 90 degrees. Find leg length AC if angle B = 45 degrees and leg BC = 19.
The tangent of a rectangular angle is the ratio of the opposite leg to the adjacent one.
tgABC = AC / BC.
AC = BC * tg45 = 19 * 1 = 19 cm.
Answer: The length of the AC leg is 19 cm.
