Answer:

  • 52°

Step-by-step explanation:

We know that sine and cosine are equal when angles are complementary.

  • sin 38° = cos m
  • sin 38° = cos (90° - 38°) = cos 52°
  • cos m = cos 52°
  • m = 52°

sin and cos are equal when their sum is 90°

So

  • cosm=0.6125=sin38
  • cos(90-38)=sin38
  • cos52=sin38
  • m=52°
