Question

Please help me and if u need it I’ll try helping u

Answer 1

Hello!

The Pythagorean Theorem is a²+b²=c². A and b are the legs, and c is the hypotenuse. we already know the hypotenuse, so we will subtract.

82²-80²=a²

6724-6400=324

√324=18

Therefore,
`\boxed {a=18}`

I hope this helps!

Answer 2

So pythagorean theorem is an equation used for right triangles to find missing sides. The equation is
`leg^2+leg^2=hypotenuse^2` . Since we know that 82 is the hypotenuse and a and 80 are our legs, we can form the equation as such:
`a^2+80^2=82^2`

Firstly, solve the exponents:
`a^2+6400=6724`

Next, subtract 6400 on both sides:
`a^2=324`

Next, square root both sides and your answer will be a = 18.
