Question

solve this problem and tell me ​

Answer 1

Answer:

<BOC+<COD+<BOE=180°

<BOC+90°+72°=180°

<BOC+162=180°

<BOC=180°-162°

<BOC=18°

Answer 2

Hi
Here’s the answer
Hope it is helpful
Mark me brainliest
Straight angle measures 180 degree
Angle COE = 180 degree
In angle COE ,angle COD is 90 degree and angle BOE is 72 degree
Angle COD+ Angle DOB+ angle BOE=180
90+ angle DOB+ 72=180
162+ angle DOB= 180
AngleDOB= 180-162
Angle DOB=18 degree
Angle BOC contains 2 angles named angle COD & angle DOB
Angle BOC= angle COD+ angle DOB
= 90 + 18
Angle BOC = 108 degree
=
