Step-by-step explanation:

Answer:

∠ C ≈ 22.6°

Step-by-step explanation:

Since Δ ABC is right at B

Using the sine ratio in the right triangle

sinC = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{AC}[/tex] = [tex]\frac{5}{13}[/tex] , then

∠ C = [tex]sin^{-1}[/tex] ( [tex]\frac{5}{13}[/tex] ) ≈ 22.6° ( to 1 dec. place )
