Help me please........

Answer:
∠ XZY ≈ 23.6°
Step-by-step explanation:
Using the sine ratio in the right triangle, that is
sinXZY = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{XY}{YZ}[/tex] = [tex]\frac{6}{15}[/tex] , then
∠ XZY = [tex]sin^{-1}[/tex] ([tex]\frac{6}{15}[/tex] ) ≈ 23.6° ( to 1 dec. place )
