Solving Right Triangles

Question

Solve the right triangle. Round decimal answers to the nearest tenth.

KL ≈ ___, ML ≈ ___∘, m angle K = ___∘

Answer 1

To find KL, use the sine function:

sin(40°) = KL/8

Solve for KL. Use your calculator to find sin(40°).

To find ML, use the cosine function:

cos(40°) = ML/8

Solve for ML.

To find angle K, remember that angles M + L + K = 180°. You already know angles M and L so finding K is easy.
