Question

Please Help Me ASAP
what is X

Answer 1

Simple!

Explanation:

The triangle is obviously a right triangle, meaning, we can use the Pythagorean Theorem to solve for x!

(The Pythagorean Theorem is where
`a^2=b^2+c^2`, or the length of the hypotenuse (side opposite to the 90 degree angle) squared is equal to the length of one leg squared plus the other leg squared).

To put it simply:

`x^2=20^2+5^2`

Now to solve!

`x^2=400+25\\x^2=425\\x=√(425) \\x=5√(17)`

This cannot be simplified further, so that's your answer!

Hope this helps!

Answer 2

how to solve: 20^2+5^2=x^2, then you take the square root, therefore x=20.62
