Answer:
Step-by-step explanation:
∠CGH = 14° {Vertical angles are congruent}
∠EGH = ∠EGC + ∠CGH
= 78 + 14
= 92
GH // EC and BG is transversal.
∠BEC = ∠EGH {Corresponding angles are congruent}
4x = 92
Divide both sides by 4
x = 92/4
x = 23°
In the diagram, P1P2 and Q1Q2 are the perpendicular bisectors of AB and BC, respectively. A1A2 and B1B2 are the angle bisectors of ∠A and ∠B, respectively <span>the center of the circumscribed circle of ΔABC is P </span><span>because both perpendicular bisectors go through the center
where they cross must be the center.</span><span>
