Answer:
x = 7/[tex]\sqrt{2}[/tex] or 4.949747468
Step-by-step explanation:
45-45-90 triangles have a specific pattern.
The smaller sides are x, & the hypotenuse is [tex]x*\sqrt{2}[/tex]
With this knowledge, we know we have to divide the hypotenuse by [tex]\sqrt{2}[/tex] to get the smaller sides, so we divide 7 by the [tex]\sqrt{2}[/tex] to find x.
