Diagram not accurately drawn

70 degrees

Step-by-step explanation:

i got a 30 degrees because its a straight line and 180-150=30

and same for 40 degrees

and 110 because its a triangle so inner angles have to add up to 180 so 180-(40+30)

70 = 1/2 of 360-(110+110)

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
