Question

â€‹I asked a question 5 times an this forum
Before asked the experts I had done it my self also My answer
matched to the answer given by Neha Sethi ma'am at the last
question asked by me (i e: x= 128/40) But it didn't match with the
condition of the question Actually this question was asked by One
of my Online Math Tutor and was HW to me I had tried a lot but
didn't get the accurate an answer Then mother advised me to ask the
meritnation experts to get the answer as I was completely tensed
due that question Let me sent the fig again as shown in the live
class

He had told us that It has been not given that GOE is a line and
that is why we have to consider The arrows extended from point O as
rays Before he had made us under stood that in a line each side
would be 180 degrees, aand when 2 rays meet they a straight line
even if Each side would be of 179 99999

As told by Neha Sethi ma'am I
am sending the following Please ma'am do reply this and please do
not contact to any of my Maths tutors Plz,Plz

Dear Student,

Let ∠COE=xThus ∠BOG=x+10Since OD bisects ∠COE⇒∠COD=∠DOE=x2Now, ∠BOG+∠BOC+∠COD+∠DOE+∠EOF+∠FOG=360°⇒∠BOG+∠COD4+90°+∠COD+∠DOE+70°+3∠BOG=360°⇒x+10+x24+90+x2+x2+70+3x+10=360⇒x+10+x8+160+x+3x+30=360⇒5x+x8+200=360⇒40x+x8=360-200=160⇒41x8=160⇒41x=160×8⇒41x=1280⇒x=128041

According to the angles marked in figure, the given angles can
never be integral multiples of 10 Kindly recheck the statement
