Step-by-step explanation:
a)
82+OCE=90°{ tangent}
0CE=8°
OCE=OEC (base angle of isosceles triangle r equal}
8+8+a=180°(sum of angle of triangle)
a=180-16
a=164°
b)d+BEC=180°
BEC=122°
BEO=BEC-OEC
b=114°
stay safe healthy and happy.
Answer:
CEO=ECO=90-82
=8
COE=180-(16)
=164
a=164
DBO=DCO=90
BOC=180-58
=122
BOE=360-(122+164)
=74
b=180-74/2
=53
