Answer 1

40 degree because total sum is 180 then already we know two angles by adding them tipo 180 we will get 40 degree

Answer 2

Answer:

option (b) 40°

Step-by-step explanation:

As it is given that AB is a straight line the total angle measure = 180°

Therefore:

40 + 100 + x = 180°

140 + x = 180°

x = 180 - 140

x = 40°
