the answer follows :
Step-by-step explanation:
we know that
the sum of all angles = 180
5x + 20 + 75 = 180
5x + 95 = 180
5x = 180 - 95
5x = 85
only, x = 85÷5
x = 17
85 + 20 + 75 =180 .
2. it is a complete angle,
so, we know that sum of all angles = 360 degree.
65 + 2x + 75 + x +3x = 360
65 +75 +6x = 360
6x + 140 = 360
6x = 220
220 + 65 + 75 = 360.
