Answer:
x = 10
Step-by-step explanation:
if there 2 same triangle then they are right triangle
By using Pythagorean theorem for 1 of right triangle, we have
=
+ ![(\frac{x}{2}) ^{2}](https://tex.z-dn.net/?f=%28%5Cfrac%7Bx%7D%7B2%7D%29%20%5E%7B2%7D)
74 = 49 + ![\frac{x^{2}}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B2%7D%7D%7B4%7D)
74 - 49 = ![\frac{x^{2}}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B2%7D%7D%7B4%7D)
25 = ![\frac{x^{2}}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B2%7D%7D%7B4%7D)
therefore, x =
=
= 10
