Answer 1

Step-by-step explanation:

A) sum of the angles in a triangle = 180 degree

80 + 45 + x = 180 degree

x = 180 - 125

x = 55 degree

55 degree + a degree in = 180 degree bcoz sum of the angled in a straight line = 180 degree

a degree = 180 - 55

a = 125 degree

B) 20+ 20 + x = 180

x = 140

b + 140 = 180

b = 40 deg

c) 180deg -134 deg= 46 deg

46 + 86 + c = 180

c deg = 180 - 132

c deg = 48 deg
