Answer:

∠ R ≈ 53°

Step-by-step explanation:

Using the sine ratio in the right triangle

sin R = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{ST}{SR}[/tex] = [tex]\frac{7.7}{9.7}[/tex] , thus

∠ R = [tex]sin^{-1}[/tex] ([tex]\frac{7.7}{9.7}[/tex] ) ≈ 53° ( to the nearest degree )

Answer:

Step-by-step explanation:

You might just duh me but the answer is obviously less than 7.7 but greater that anything above one so what you do is process of elimination hope this way of solving helps
