Question

in a figure AOB and COD. are two intersecting lines OE is a ray and x:y:z=2:3:4 . then find the value of all the missing angles​

Answer 1

Answer:

Solution

∠BOE+∠AOE=180∘ (Supplementary Angles )

∠AOE=180∘−80∘=100∘

and ∠BOD=∠AOC=30∘ (Vertically Opposite Angles)

Hence, ∠EOC=100∘+30∘=130∘
