Answer 1

C) u = 9 ; v =9

Explanation:

45-45-90 is a special isosceles right triangle.

The ratio of sides are,

1 : 1 : √2

So, the length of the congruent sides are x and the length of hypotenuse is √2x.

hypotenuse = 9√2

√2x = 9√2

`\sf x =(9√(2))/(√(2))\\\\\\ x = 9`

u = x

u = 9

v = x

x = 9
