Question

In the figure,the sum of angle 1 angle 2 and angle 3 is​

Answer 1

Step-by-step explanation:

angle 1+angle 2+angle 3= 360°-angle 4

= 360° -60°

= 300°

Answer 2

Answer:

angle 1 + 60 is equal to 180 degree ( linear pair of angles )

angle 1 is equal to 180 - 60 and angle 1 is equal to

120

angle 2 is equal to 60 degree (vertically opposite angle)

angle 3 is equal to angle 1 (vertically opposite angle)

angle 3 is equal to 120
