Since ∠1 and ∠3 are a vertical pair, they are congruent angles. This means that:
∠1 = ∠3
(4x + 26)° = 98°
4x + 26 = 98
4x = 72
x = 18
Thus, the value of x is 18.
In a geometric figure two intersecting lines creating four angles. If ∠1 and ∠3 are a vertical pair, m∠1=(4x+26)° , and m∠3=98° , what is the value of x ?(1 point)
