WebLet us show that ∠2 and ∠3 are supplementary. Since ∠1 and ∠2 form a linear pair, then they are supplementary. That is, ∠1 + ∠2 = 180°. By the Alternate Interior Angle Theorem, ∠1 = ∠3. Thus, ∠3 + ∠2 = 180°. Therefore, ∠2 and ∠3 are supplementary. Same-Side Interior Angles Theorem John Ray Cuevas The Converse of Same-Side Interior … Web23 mei 2024 · Best answer According to question ∠1 + ∠2 + ∠3 + ∠4 = 360° (Angles formed at a point is 360°) But ∠1 + ∠2 + ∠3 = 230° (given) (∠1 + ∠2 + ∠3) + ∠4 = 360° 230° + ∠4 = 360° ∠4 = 360° – 230° ∠4 = 130° But ∠1 + ∠4 = 180° (linear pair axiom) ∠1 + 130°= 180° ∠1 = 180°- 130° = 50° ← Prev Question Next Question → Find MCQs & Mock Test clock cards 106532
