Answer 1

Step-by-step explanation:

In num 1 angle BOC and angle AOC forms linear pair and it has sum 180

In num 2 2x+75+x forms staight line and it also has sum 180

Answer 2

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.
