In the given figure determine the value of y and hence find (EOB,(FOA and (COD Share with your friends Share 1 Neha Sethi answered this From the figure ∠EOF=∠COD Vertically opposite angles⇒∠EOF=∠COD=5y ....*Now ∠BOC+∠COD+∠DOA=180° Linear pair⇒5y+5y+2y=180°⇒12y=180°⇒y=15° ...1Now ∠FOE+∠EOB+∠BOC=180° Linear pair⇒5y+∠EOB+5y=180° ⇒∠EOB+10y=180°⇒∠EOB+1015° =180° using 1⇒∠EOB+150°=180°⇒∠EOB=30°Now, ∠EOF+∠FOA+∠AOD=180° Linear pair⇒5y+∠FOA+2y=180°⇒∠FOA+7y=180°⇒∠FOA+715°=180° using 1⇒∠FOA=180°-105°=75°So, ∠FOA=75°and ∠EOF=∠COD=5y using *⇒∠COD=5y ⇒∠COD=5×15°=75° using 1⇒∠COD=75° 1 View Full Answer
