Answer: x=1991/10
Step-by-step explanation: Step 1: Simplify both sides of the equation.
9x+10=2001−x
9x+10=2001+−x
9x+10=−x+2001
Step 2: Add x to both sides.
9x+10+x=−x+2001+x
10x+10=2001
Step 3: Subtract 10 from both sides.
10x+10−10=2001−10
10x=1991
Step 4: Divide both sides by 10.

Answer:
x = 136
Step-by-step explanation:
The angle marked x° is half the sum of the intercepted arcs:
x° = (130° +142°)/2 = 272°/2
x = 136
