Quiz: Module 10 Final Qu This Question: 1 pt Solve the right triangle. b 1.42 c 3.96 Ass (Round to the nearest tenth as needed B ° ound to the nearest tenth as needed.) a ound to the nearest hundredth as needed.) Enter your answer in each of the answer boxes

Solution

b = 1.42 ; c= 3.96

So, c is the hyppotenuse

Its aright angled triangle a^2 = c^2 - b^2 = 3.96^2 - 1.42^2 = 13.66

a = 3.69 = 3.7

cosA = b/c = 1.42/3.96

A = 68.98 = 69 deg

B = 180 -90 -69 =21 deg
