Question

How do I find measurements of angle 1-5?

Answer 1

∠1 + 52° = 180° (Opposite angles are supplementary)

=> ∠1 = 180° - 52°

=> ∠1 = 128°

∠2 = 52° (Alternate interior angles)

∠3 = 47° (Alternate interior angles)

∠4 = 180° - ∠3 (Supplementary angles)

=> ∠4 = 180° - 47°

=> ∠4 = 133°

∠5 = 180° - (52° + 47°) (Supplementary angles)

=> ∠5 = 180° - 99°

=> ∠5 = 81°
