Question

Tamika builds a wooden skateboard ramp. The ramp measures 63 centimeters, and the length of its horizontal base is 60 centimeters, as shown.

In centimeters, what is the approximate height of the ramp? Round the answer to the nearest tenth of a centimeter.

Answer 1

The answer is 19.2 cm

Explanation:

Trust me its correct

Answer 2

So imma be using the Pythagorean Theorem, which is
`a^2+h^2=c^2`. The a and h variable represent the legs of the right triangle while c variable stands for the hypotenuse. And since we have one of the legs and the hypotenuse, we are solving for the other leg.

So first we are gonna plug in 60 and 63 in their appropriate spots:
`60^2+h^2=63^2`

Solve the exponents to get
`3600+h^2=3969`

Subtract 3600 on each side to get
`h^2=369`

To cancel out the squared power, you have to square root each side of the equation, and your final answer should be
`h=19.2`cm
