Answer:

x=50.7°

Explanation:

Use the given angle of x° to find which trigonometry ratio to use. We are given the side adjacent to the angle and the hypotenuse. Therefore, we use the cosine ratio:


cosineX=(adjacent)/(hypotenuse)

Insert the given values:


cos.x=(19)/(30)

In order to fin the angle, use the inverse:


x=cos^(-1)((19)/(30) )

Insert the equation into a calculator:


x=50.70351976

Round to the nearest tenth:


x=50.7

:Done
