Q. 5 C5.0( 1 Vote )

Find the values of x, y in the following figures.


Answer :

Given: AOD = y° ,DOC = 90°,COB = x° ,AOE = 3x and BOE = 60°


Here AB is the straight line.


AOE and BDC are linear pair.


ADC + BOE = 180°


3x + 60° = 180°


3x = 120°


x = 40°


Also, AOD, DOC and BOC are linear pair.


AOD + DOC + BOC = 180°


y + 90° + x° = 180°


y = 90° - 40°


y = 50°
