What is the length of side s of the square shown below?

C

Step-by-step explanation:

The Pythagorean Theorem tells us that

a^2 + b^2 = c^2

a = b = s because a right angle and a 45 degree angle leaves only 45 degrees which means that both acute angles are 45 degrees

c = 2

2s^2 = 2^2         Divide by 2

s^2 = 4/2

s^2 = 2                Take the square root of both sides.

sqrt(s^2) = sqrt(2)              

s = sqrt(2)

its not b
