Answer:
x=11
Step-by-step explanation:
- The angles directly opposite 80 and 60 are also 80 and 60 respectively, because they are vertical angles
- Now the triangle we see there, on the bottom left corner the angle is 80 degrees and the bottom right the angle is 60 degrees
- Theorem states that the sum of angles in a triangle is 180 degrees
- So 80 degrees plus 60 degrees plus the angle (x+51) is equal to 180

Think of a vertical number line. The positive values count down as we move down this number line. The negative numbers count up, so to speak, as we move down the number line. So we have -1, -2, -3, ... as we move down. This indicates that -5 is <u>not</u> smaller than -7.
Diagram is below.
