Question

I NEED HELP!!! Can someone please help me

Answer 1

I’m pretty sure it’s 7

Answer 2

x = 4
`√(2)`

Explanation:

Here you have to use the Pythagorean Theorem.

Pythagorean Theorem: a^2 + b^2 = c^2

STEP 1: Define your variables

a and b are the legs of the triangle, and c is the hypotenuse

a = 7

b = x

c = 9

STEP 2: Plug the variable into the equation

7^2 + x^2 = 9^2

STEP 3: Solve

7^2 + x^2 = 9^2

49 + x^2 = 81

49 - 49 + x^2 = 81 - 49

`√(x)`^2 =
`√(32)`

x =
`√(32)`

STEP 4: Simplify

Since the questions asks you to put it in simplified radical form, you do not have to approximate the answer, but you do have to simplify the radical.

x =
`√(32)`

x =
`√(16)` *
`√(2)`

x = 4
`√(2)`

Hope this helps
