Answer:
z = 20
Step-by-step explanation:
We need to know the fact that consecutive angles are supplementary which means that they add to 180°. So we can form an equation to solve for z.
2z + 16 + 124 = 180
→ Simplify the expression
2z + 140 = 180
→ Minus 140 from both sides to isolate 2z
2z = 40
→ Divide both sides by 2 to isolate z
z = 20
