Question

the hypotenuse of right triangle ABC, line segment AC, measures 13 cm. The line segment of BC measures 5 cm. what is the approximate difference between angle c and angle a

Answer 1

find the other leg: a²+b²=c²
5²+b²=13², b=12
sinC=12/13,
use a calculator, C=67.37
sincA=5/13, A=22.62 (notice: A and C make a total of 90)
difference: 67.37-22.62=44.75

Answer 2

Uses trigonometric ratios like the sin that is opposite over hypotenuse
