Answer:
20
Step-by-step explanation:
The whole straight line is 180 degrees. Add 3x, 2x, and 4x all together to get 9x. Then do 180/9x. This will give you 20. x=20.
Triangle= 180 degrees
Angle = 37.5 degrees
Supplement angle = 105 degrees
If you multiply the angle (37.5) by 2 and then add 30, it gives you 105. Then add 37.5 twice to make up the other two angles of the triangle and it gives you 180 total degrees as a triangle should.
