Question

Solve for a side in right triangles

Answer 1

AC = 3.76

Explanation:

The opposing side of ∠B needs to be found, where the value of the hypotenuse is given. Take the sin ratio.

• sin∠B = AC/4
• sin70° = AC/4
• 0.94 = AC/4
• AC = 4 x 0.94
• AC = 3.76

Answer 2

The answer is AC = 3.76

Explanation:

CohCahToa

Coh: sin(theta) = Opp/Hyp

sin(theta°) = AC/AB

sin(70°) = AC/4

AC = 4*sin(70°)

AC ≈ 3.758770483

AC = 3.76
