Today Mr. Harbeck said that if we haven't scribe yet we should pick a question. Here is question number 7.

7. What is the height of

the wheelchair ramp?

Give your answer to

the nearest tenth of a centimetre.

the wheelchair ramp?

Give your answer to

the nearest tenth of a centimetre.

c² - b² = a²

80² - 79² = a²

(80x80) - (79-79) = a²

6400 - 6241 = a²

159 = a²

√159 = √a²

12.6cm= a

The wheelchair ramp would be 12.6 cm tall.

Thanks for reading my scribe!
