Question

ILL BRAINLIEST YOU PLEASE HELP ME

Answer 1

Answer:

x = 7/$\sqrt{2}$ or 4.949747468

Step-by-step explanation:

45-45-90 triangles have a specific pattern.

The smaller sides are x, & the hypotenuse is $x*\sqrt{2}$

With this knowledge, we know we have to divide the hypotenuse by $\sqrt{2}$ to get the smaller sides, so we divide 7 by the $\sqrt{2}$ to find x.
