Since Z1 and Z3 are a vertical pair, they are congruent angles. Therefore, mL1 = mL3.
We are given that mL1 = (4x + 26) ° and mL3 = 98°.
Setting them equal to each other, we have:
4x + 26 = 98
Subtracting 26 from both sides:
4x = 72
Dividing both sides by 4:
x = 18
Therefore, the value of x is 18. The answer is O 18.
