Answer:

∠ A = 31.3°, ∠ C = 58.7°

Explanation:

Using the sine ratio in the right triangle

sin A =
(opposite)/(hypotenuse) =
(BC)/(AC) =
(13)/(25) , thus

∠ A =
sin^(-1) (
(13)/(25) ) ≈ 31.3° ( to the nearest tenth )

The sum of the 3 angles in a triangle = 180° , thus

∠ C = 180° - (90 + 31.3)° = 180° - 121.3° = 58.7°
