Question

Someone help me plz ty :)

Answer 1

X = 12.12

Explanation:

Use the Pythagorean Theorem for this question.

`a^2 + b^2 = c^2`

7 is one of the legs while 14 is the hypotenuse. So we set up the equation like this:

`a^2 + 7^2 = 14^2`

Square 7 and 14:

`a^2 + 49 = 196`

Minus 49 from both sides:

`(a^2 + 49) - 49 = (196) - 49`

`a^2 = 147`

Square root both sides:

`√(a^2) = √(147)`

`a = 12.12`

Therefore x is equal to 12.12

Hope this helps!!
