Question

Can someone help me with this

Answer 1

y=8.9

Explanation:

To solve this problem, we have to use the pythagorean theorem.

the formula for the pythagorean theorem is a²+b²=c²

(8)²+(y)²=(12)²

64+y²=144

y²=144-64

y²=80

y=√80

y=4√5

y=8.9

hope this helps!!

Answer 2

the answer should be 8.9

you square 12 and square the 8 and subtract them by each other
