Since ∠1 and ∠3 are a vertical pair, they are congruent.
Therefore, we can set up the equation:
4x + 26 = 98
Subtract 26 from both sides:
4x = 72
Divide by 4:
x = 18
Therefore, the value of x is 18.
In a geometric figure two intersecting lines create four angles. If ∠1 and ∠3 are a vertical pair, m∠1=(4x+26)° , and m∠3=98° , what is the value of x ?
