4) Jake plans to use a ramp to make it easier to move a piano out of the back of his truck. The back of the truck is 6 feet tall and the ramp is 10
feet long. What is the horizontal distance from the end of the ramp to the
back of the truck?*
O 10 feet
O 9 feet
8 feet
O 7 feet

134.4 centimeters

Step-by-step explanation:

This question is asking us for a missing leg on the triangle, lets call it x. Using the Pythagorean theorem (a²+b²=c²), we can figure out what value is missing (either a or b, they are interchangeable).

replace the values in the equation.

83²+x²=158²

get rid of the exponents.

6,889+ x² = 24,964.

subtract 6,889 from 24,964.

x²=18,075.

find the square root on both sides of the equation.

x=134.4432966.

I am assuming you want this rounded to the nearest tenth.

134.4 is your answer.

what is the original number? you forgot to add it.
