Answer:

Step-by-step explanation:

Angle ACB=1/2*Angle CAO

=1/2*70°

=35°

[Angle in the centre is half of the angle at the remaining circumference ]

We take the point D where it forms a 90°

So,in triangle BDC

Angle CDB=90°(linear pair)

In triangle CDB,

90°+35°+x=180°[sum of three angles in a triangle is 180°]

Therefore, x=180-90-35

x=55°[answer]

Plzz mark it as brainliest.....

mondalananya8765: If u can't understand.. Shall I do it again?

mondalananya8765: Oo... Hahaha

mondalananya8765: Can u plzz mark it as brainliest? Only if u have completely understood it?

knightwing58: what is brainliest??

knightwing58: i am new in this app so i dont know its features

knightwing58: angle CAO should be 20

knightwing58: hey r u there???

mondalananya8765: Yes angle CAO should be 20..but why?

knightwing58: because in triangle DOA- angle ADO=90,90+70+angle CAO=180 so angleCAO=20

mondalananya8765: Yes that I know... But we do not require the value of angle CAO in this sum...

Answered by priyanshi36

angle cao is 70°
CPBis 90°
70°+90°+x=180°
x=20°

knightwing58: can you tell me how angle BCD=70

knightwing58: answer is 55
