∠CEB and ∠AED are vertical angles, which means they must be equal to each other. Make them = x in an equation. The angles form a quadrilateral, so the sum of the interior angles must equal 360°.
77 + 77 + x + x = 360
Combine like terms.
154 + 2x = 360
Subtract 154 from both sides.
2x = 206
Divide both sides by 2.
x = 103
∠CEB is greater than 90°, so it must be an obtuse angle.
