Question

In right triangle ABC, ∠A is a right angle, m∠B=44∘, and AC=10. sin44∘≈0.695 cos44∘≈0.719 tan44∘≈0.966

What is the measurement of BC
If necessary, round your answer to one decimal place, like this: 42.5

Answer 1

14.4

Explanation:

Answer 2

BC = 14.4

Explanation:

let's use sin B=opp/hyp = AC/BC = 10 / x

sin44∘≈0.695

so 0.695 = 10/x multiply both sides by x

0.695x = 10 divide both sides by 0.695

x = 10/ 0.695

x = 14.39
