Find c to two decimal places and find the measure of angle B. Angle A = 58°, Side AC = 5, Side BC = 8, Find side C. Angle C is 90°.

c = 9.43 m∠B = 32°

Step-by-step explanation:

Side c = AB can be found using the Pythagorean theorem:

c² = a² + b² = 8² + 5² = 89

c = √89 ≈ 9.43

__

Angle B is the complement of angle A, so is ...

B = 90° - A = 90° - 58° = 32°

c is approximately 9.43; the measure of angle B is 32°.
