Question

You are going to use an incline plane to lift a heavy object to the top of a shelving unit with a height of 8 ft. The base of the incline plane is 11 ft from the shelving unit. What is the length of the incline​ plane?

Answer 1

21

Explanation:

19+10 = 21

Answer 2

Explanation:

This is a right triangle. The floor and the shelf would form a 90 degree angle. The Pythagorean theorem states that the sum of the squares of the legs is equal to the square of the hypotenuse.

8^2+11^2=x^2

185=x^2

`x=√(185)`
