Which equation can you use to solve for Theta in the figure shown?

sine (theta) = StartFraction 54.8 Over 45 EndFraction

sine (theta) = StartFraction 31.2 Over 54.8 EndFraction

sine (theta) = StartFraction 45 Over 54.8 EndFraction
A right triangle is shown. 2 sides have lengths of 45 feet and 31.2 feet and the hypotenuse has a length of 54.8 feet. The angle opposite to the side with length 45 feet is theta.
