Answer:
B. 23
Explanation:
The sum of the angles that creates a straight line is 180 degrees. So we can write the equation
5x + 65 = 180
Solve for x by first subtracting 65 on both sides
5x = 115
Then divide both sides by 5
x=23
Total = 180° for a supplementary angle.
5x = 180 - 65
x = 115/5
x = 23
