Question

Given that angle a = 53°, work out x

Answer 1

Step-by-step explanation:

∠ABD + ∠DBC = 180° (Linear pair of angles) ⇒ x + y = 180° ⇒ 53°+ y = 180° (∵ x = 53”) ⇒ y = 180° – 53° ⇒ y = 127°Read more on Sarthaks.com - https://www.sarthaks.com/171974/in-the-given-diagram-abc-is-a-straight-line-i-if-x-53-find-y
