Question

Solve the right triangle shown in the figure. (Round your answers to two decimal places.)

Answer 1

Explanation:

sin A =
`(a)/(c)`

sin 9.4° =
`(20.5)/(c)` ⇒ c = (20.5) / (sin 9.4°) ≈ 125.52

tan A =
`(a)/(b)`

tan 9.4° =
`(20.5)/(b)` ⇒ b = (20.5) / (tan9.4°) ≈ 123.83

m∠B = 90° - 9.4° = 80.6°

m∠C = 90°
