Answer:

5*sqrt2

Step-by-step explanation:

It would be same because both sides are equal in length sinve it is a 45-45-90 triangle

Answer:

x = 7

Step-by-step explanation:

Since it is a 45- 45- 90 triangle then it is isosceles with the 2 legs congruent, both x

Using Pythagoras' identity in the right triangle

x² + x² = (7[tex]\sqrt{2}[/tex] )²

2x² = 98 ( divide both sides by 2 )

x² = 49 ( take square root of both sides )

x = [tex]\sqrt{49}[/tex] = 7
