Answer:
Step-by-step explanation:
This is a Pythagorean Theorem Question
c^2 = a^2 + b^2
c= sqrt(5)
a = x
b = x This is an isosceles right triangle. The vertical side and the horizontal side are equal.
x^2 + x^2 = sqrt(5)^2
2x^2 = 5 Divide both sides by 2
x^2 = 5/2 Take the sqrt of both sides.
√x^2 = √5 / √2 Multiply right side by √2 on both top and bottom
x = √5*√2 / √2*√2
x = √10 /2
