Question

I need help ill give brainliest

Answer 1

Answer:

Step-by-step explanation:

For the first question, the first one is correct because:

a^2+b^2=c^2

where a and b are the two legs and C is the hypotheneuse of the triangle. 8 and y are the leg sides in this case.

So the equation is

8^2+y^2=12^2

For the second question:

we can change the equation to ;

y^2=12^2-8^2 ->

y^2=144-64 ->

y^2=80

Answer 2

Answer: The first equation can be used to find the answer.

The solution to y^2 is 80
