Answer:
the answer should be 8.9
you square 12 and square the 8 and subtract them by each other
y=8.9
Step-by-step 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
hope this helps!!
