Question

The latter shown in the picture below is 10 m long. As shown in the picture, the bottom of the ladder is 5 m from the base of the building. Use Pythagorean theorem and find how high up the building the window is where the ladder is reaching. round your answer to two decimal places

Answer 1

Answer: sqrt75 or 8.66

Explanation:

The pythagorean theroem states the a^2+b^2=c^2 in this case 5^2+b^2=10^2 where b is the height of the building. So to solve this just simplify

5^2+b^2=10^2

25+b^2=100

b^2=75

`√(b)^2`=
`√(75)`

b=8.66
