A right triangle has side lengths AC = 7 inches, BC = 24 inches, and AB = 25 inches.

What are the measures of the angles in triangle ABC?

(a.) m∠A ≈ 46.2°, m∠B ≈ 43.8°, m∠C ≈ 90°

(b.) m∠A ≈ 73.0°, m∠B ≈ 17.0°, m∠C ≈ 90°

(c.) m∠A ≈ 73.7°, m∠B ≈ 16.3°, m∠C ≈ 90°

(d.) m∠A ≈ 74.4°, m∠B ≈ 15.6°, m∠C ≈ 90°

plz help every time i try to do the problem my answer doesnt show up but i have no idea what im doing wrong... 
its not D tho, i know that much

The measures of triangle ABC are m∠A = 73.7°,  m∠B = 16.3°  m∠C = 90°

What is a right angle triangle?

A right-angled triangle is a triangle with the largest of its angle 90° and the side facing this angle is usually called the hypotenuse.

Analysis:

side AC is the side facing the smallest angle, side BC faces the semi-largest angle and side AB faces the largest angle which is 90°.

using sine rule,

\(\frac{25}{sin 90}\) = \(\frac{24}{sin A}\)

25 sin A = 24 sin 90

sin A = 24/25

A = arc sin(24/25) = 73.7°
\(\frac{25}{sin 90}\) = \(\frac{7}{sin B}\)

25 sin B = 7 sin 90

sin B = 7/25

B = arc sin(7/25)  = 16.3°

In conclusion, the measures of the angles of the triangle are m∠A = 73.7°,  m∠B = 16.3°  m∠C = 90°
