Answer:
1)reflex of angle(1+2) = 270°
Step-by-step explanation:
so it is given that all 3 lines are parallel
so let take left line and middle line as parallels
then angle 35= angle 1 ( alternate interior angles)
so angle 1= 35°
then same as before take right line and middle line as parallels
then angle 55 = angle 2 ( alternate interior angles)
so angle 2 = 55°
so we have to find reflex of angles 1+2
so reflex angles of X = 360 - X
so reflex of 1+2 = 360 - (35+55)
= 360 - 90
= 270°
so reflex of angle(1+2) = 270°
