Answer:

  • B = 65°
  • AB = 37.859
  • AC = 34.312

Explanation:

The given side is opposite the given acute angle in this right triangle, so the applicable relation is ...

Sin(25°) = CB/AB

Solving for AB, we get ...

AB = CB/sin(25°) ≈ 37.859

__

The relation involving the other leg of the triangle is ...

Tan(25°) = CB/AC

Solving for AC, we get ...

AC = CB/tan(25°) ≈ 34.312

__

Of course, the missing angle is the complement of angle A, so is 90-25 = 65 degrees.
