Amelia is looking at the top of a lighthouse. She knows she is 32 feet from the base of the lighthouse. if she is 62 inches tall and the angle of elevation is 37°, how tall is the lighthouse? Round to the nearest tenth of a foot.

The range would be 13 because you’re finding the difference

1. use commutative property to reorder the terms.2x+81=0.2. move the constant to right side by adding its opposite on both sides. 2x+81-81=0-81.2x=(-81).3. divide the equation on both sides.2x ÷ 2 = 81 ÷ 2.x = -81/2. your answer is -81/2. if you need to simplify it into a decimal, it’s -40.5.
