Question

Lewis needed to find the difference in lengths between the hypotenuse and the longest leg of this triangle. His work is shown below.
Triangle A B C. Side B C is 16 and side A C is 12. Hypotenuse A B is labeled c.
12 squared + 16 squared = c squared. 144 + 256 = c squared. 400 = c squared. StartRoot 400 EndRoot = c. 200 = c. Difference: 200 minus 12 = 188.

Answer 1

Answer:

He simplified \sqrt{400}

400

incorrectly. It should be 20 instead of 200.

Step-by-step explanation:

Lewis made a mistake on the 5th line of his solution.

Square root of 400 is 20, NOT 200.

So the answer for cc would be 20.

And the difference between hypotenuse (20) and longer leg of the two (16) is 20-16=420−16=4
