Answer 1

Hey there!

For a complete angle the angle measure is 360degree

Thus x=360-(30+40+140+90)

x=360-300=60 degree

Answer 2

Answer:

x = 60°

Step-by-step explanation:

sum of 90° , 30° and x ° must be 180° as they are linear pairs.

90° + 30° + x = 180°

x = 180° - 120° ( as 90+30 is 120)

x = 60°

Thus , x = 60°
