Help me please asap!!!!!

Answer 1

Answer:

x=10

Step-by-step 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.

$7^{2}+\frac{1}{2} x^{2} =\sqrt{74}^{2}$

$49+\frac{1}{2} x^{2} =74$

$\frac{1}{2} x^{2} =25$

$\frac{1}{2} x=5$

$x=10$

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