Question

prove that AEB =60°​

Answer 1

Answer is given below

Answer 2

Step-by-step explanation:

since OC=OD=CD

it is a equilateral triangle

OCD = 60°

let OAC be 'x'

then ACO = x (since OA = OC)

similarly,

DBO = BDO = y

y+x+60=180 ( opposite angles are supplementary)

x+y=120

in triangle ABE

x+y+AEB=180 (A.S.P of triangle)

120+AEB=180

AEB=60°

hence proved
