2/3 of a right triangle is 60 degrees. Then x + (x+20) + 60 = 180 total.
2x + 80 = 180, so 2x = 100 and x = 50. The angles are 50, 70 and 60 (degrees)

Step-by-step explanation:
Solve
Let's solve your equation step-by-step.
4x−2=2x
Step 1: Subtract 2x from both sides.
4x−2−2x=2x−2x
2x−2=0
Step 2: Add 2 to both sides.
2x−2+2=0+2
2x=2
Step 3: Divide both sides by 2.
2x
