Question

Help me please asap!!!!!

Answer 1

x=10

Explanation:

In order to solve this equation we must break it down. This question is going to require the Pythagorean theorem
`a^(2) +b^(2)=c^(2)`. To use this we need a right triangle which happens to be half of the triangle shown. Now we can plug in the numbers.

`7^(2)+(1)/(2) x^(2) =√(74)^(2)`

`49+(1)/(2) x^(2) =74`

`(1)/(2) x^(2) =25`

`(1)/(2) x=5`

`x=10`

This ends in x equaling 10. I hope this helps you!
