Asurveyor holds a laser range finder 3 feet above the ground and determines that the range finder is 112 feet from a building and 131 feet from the top of the building. what is the height (h) of the building? round your answer to the nearest tenth.

The range finder is 112 feet from the building ( adjacent ) and 131 feet from the top of the building ( hypotenuse ).
We will use the Pythagorean theorem:
x² = 131² - 112²
x² = 17,161 - 12,544
x² = 4,617
x  = √ 4,617
x = 67.948
The height of the building:
h = x + 3 = 67.948 + 3 = 70.948 ≈ 70.9 ft ( to the nearest tenth )
h = 70.9 feet.

Ithink the answer should be b.
