Answer:

B. 5

Step-by-step explanation:

Use the pythagorean theorem to solve: a^{2}+b^{2}=c^{2}.

a^{2}+12^{2}=13^{2}

a^{2}+144=169

Subtract 144 from 169.

a^{2}-144=169-144

a^{2}=25

Square root to get a.

\sqrt{a}=\sqrt{25}

a= 5

The angles of a triangle will always add up to be 180 degrees total.

x + 82 + x + 82 + 40 = 180
2x + 164 + 40 = 180
2x + 204 = 180
Subtract 204 from both sides.
Think of it as “180 + (-204)”
2x = -24
Divide each side by 2.
x = -12

Answer: x = -12
