Question

Measure of the side of the right triangle whose length is designated by a lowercase letter round answers to the nearest whole number.

Answer 1

Adjacent leg = b (your variable)

Hypothenuse = 220 inches

angle between adjacent leg and hypothenuse = 34 degrees

sin (34°) = adjacent leg /  hypothenuse = b / 220 inches =>

=> b = 220*sin(34°) inches = 123.02 inches

Answer: b = 123.02 inches
