Answer:

Step-by-step explanation: Since we know the angle of a line is 180 degrees. We can use that.

1. 180-30 because we already know that angle is 30 degrees.

2. We are left with 150 degrees so we know the large angle is 150 degrees to check we do this.

3. 150=2x+50

4. 100=2x Divide both sides by two and get

5. x=50

Answer:

50

Explanation:

We know angles in a straight line add up to 180, therefore:

2x + 50 + 30 = 180

2x + 50 = 180 - 30

2x + 50 = 150

2x = 150 - 50 = 100

2x = 100

x = 50
