Question

Analyze the diagram below and complete the instructions that follow.

Answer 1

The side opposite the left 45 degree angle is 8 as well since the 2 base angles are equal.

Use s^2 + b^2 = c^2
Solve for c
8^2 + 8^2 = c^2
64 + 64 = c^2
128 = c^2
c = sqrt(128)
c = sqrt(64 * 2)
c = 8 sqrt(2)
c = 11.31

Answer 2

A right triangle with 45 degree angles, the hypotenuse would be the length of side times sqrt 2

so for this one x = 8√2
