Answer:
(13) Equation: x + (x+2) + 72 = 180
Answer: x = 53
(14) B = 55 degrees
Explanation:
(13) The sum of the angles in any triangle is always 180 degrees, so you can find the sum of the given angles and set up an equation, then solve
x + (x+2) + 72 = 180
2x + 74 = 180
2x = 106
x = 53
(14) If x = 53 and angle B is equal to to x + 2, you can just add 2 to 53 and get the answer that the measure of angle B is 55 degrees
