Question

find the value of 2u,x,y


it is very important....it will be yours most kindness if you can give answer...and this answer will add into brainlist​

Answer 1

Step-by-step explanation:

in the given figure triangle AOD= u and AOC =u also

DOB,=x

BOE=y

COE=75

and the complete angle is 360'

so, x+y+2u+75 =360'

by the linear pair

DOE+DOB+COE=180'

x+y+75=180'

x+y=180-75

x+y=105

105/2=50.5

AOC+AOD+DOB+BOE+EOC=360'

2u+55.5+55.5+75=360'

2u+105=360'

2u=360-105

2u=255

u=255/2

u=125.5
