The measure of angle BAC can be calculated using the equation sine super negative 1 (StartFraction 3.1 Over 4.5 EndFraction) equals x.

Triangle A B C is shown. Angle A C B is a right angle. The length of hypotenuse A B is 4.5 inches and the length of C B is 3.1 inches. Angle C A B is x.

What is the measure of angle BAC? Round to the nearest whole degree.

Sin(angle) = Adjacent leg / Hypotenuse

Sin (x) = 3.1 / 4.5

X = arcsin(3.1/4.5)

x = 43.54

Round to nearest degree = 44 degrees

Answer:

44 degrees
