What do A and B equal?

PLEASE ANSWER I WILL GIVE A BRAINLIEST

a=2

b=2

Step-by-step explanation:

This is a special 45-degree right triangle. Two angles equal 45 degrees, and then there is a right triangle. In these triangles, the hypotenuse is equal to where k is equal to the legs (a and b). So, to find the legs divide by . This equals 2, and since a and b are congruent both a and b equal 2.

x is variable or an unknown value to find

example:

2x = 5 which means x = 3
