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

BC = 14.4

Step-by-step 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  

b

step-by-step explanation:

b

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
