Question

Find the unknown measures. Round lengths to the nearest hundredth and angle measures to the nearest degree.

Answer 1

AB = 4.62 m∠A = 22° m∠B = 68°

Explanation:

Tan A = 1.7/4.3 = .39534...

m∠A = arctan .39534... ≅ 22°

m∠B = 90 - 22 = 68°

AB =
`\sqrt{1.7^(2) + 4.3^(2) } = √(2.89 + 18.49) = √(21.38) = 4.62`
