Answer:
120
Explanation:
Information we need to know:
Angles on a straight line add up to 180
Transverse angles are the same
1) Find the missing angles
To find x we need to find the value of the missing angle.
We can see that the missing angle is transversed to the angle highlighted 40.
This gives us the missing value to be 40
2) Find the values of x
The line which x is on is a straight line.
As it is a straight line the angles all must add up to 180
We already know that the two missing angles are 20 and 40 so to find x we have to add them together then subtract from 180
- 20 + 40 = 60
- 180 - 60 = 120
Hope this helps, have a lovely day! :)
