egoroff_w [7]

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

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

74 = 49 + $\frac{x^{2}}{4}$

74 - 49 = $\frac{x^{2}}{4}$

25 = $\frac{x^{2}}{4}$

therefore, x = $\sqrt{25*4}$ = $\sqrt{100}$ = 10
