5). What is the answer?​

Answer 1

c=15m.

Step-by-step explanation:

For this problem, you'll want to use the Quadratic Formula, remember a2+b2=c2.

Since you have the two sides of your triangle, you're trying to find the hypotenuse (always c), which is the longest side of the right triangle, and also the diagonal in this problem. plugging in 9 for a and 12 for b we get:

92+122=c2 from here we can simplify to:

81+144=c2

c2=225 then we want to take the square root of both sides to obtain c.

Therefore, c=15m.
