Question

solve for m∠mkl.
answer
m∠mkl =

Explanation:

Step1: Identify angle - relationship

Assume the right - angle is 90°. If one part of the right - angle is 40°, and we want to find ∠MKL.

Step2: Use angle subtraction

The whole right - angle is 90°. Let ∠MKL be the unknown angle. We know that 90°=∠MKL + 40°. So, ∠MKL=90° - 40°.
