Question

please give me correct answer I will mark you as brainlist answer.
1) In the figure , if angle ADC = ( 2x-13 ) and angle BOC = ( 3x-12 ) , find all four angles.
​

Answer 1

Answer:

angle COA= angle BOD(Vertically opposite angle)

angle COB= angle AOD(Vertically opposite angle)

bod=coa=2x-13

cob=aod=3x-12

Step-by-step explanation:

all angles =360⁰

2(2x-13+3x-12)=360

2x-13+3x-12=180

5x-25=180

5x=180-25

5x=155

x=155/5

x=31

coa=bod=2*31-13=49

boc=aod=3*31-12=81

Hope it helps
