<span>The side opposite the 30 degree angle is half of the hypotenuse.
a^2 + b^2 = c^2 =>
a^2 + (c/2)^2 = c^2
12^2 + c^2/4 = c^2
4*12^2 + c^2 - 4c^2 = 0
576 - 3c^2 = 0
- 3c^2 = - 576
c^2 = 192
c = 8√3

Step-by-step explanation:
Answer:
the interior angles of a pentagon = 540
540/5 = 108

180- 108 = 72
72/2 = 36
X = 36°
