OK so I chose number 7

7.What is the height of the wheelchair ramp? Give your answer to the nearest tenth of a centimeter.

Formula

c² - b² = a²

80² - 79² = a²

(80x80) - (79-79) = a²

6400 - 6241 = a²

159 = a²

√159 = √a²

12.6cm= a

Simple sentence answer- The height of the wheel chair ramp would be 12.6 cm high

PLEASE COMMENT THANK YOU !

Good job Gilbert! The only thing I noticed, was in your formula, I think you accidentally put (79-79) when it is supposed to be (79x79). Other than that, you did really good! Keep up the good work my friend.

Good job Gilbert ! , i liked how you but a , b and c inside the right angle . You explained it good although it's 79 X 79 .
