pls iska answer dijiya urgent hai​

Answer 1

Answer:

HOW TO SOLVE?

Angle DCO = 2x

Angle ABO = 3x + 10

AB = AO

OC = OD

SOLVING FOR X:

Angle ABO = Angle AOB

(Angles opposite to equal sides are equal)

Angle OCD = Angle BAO (Alternate angle)

3x + 10 + 3x + 10 + 2x = 180°

(Angle sum property of a triangle)

8x + 20° = 180°

8x = 180°-20°

8x = 160°

x = 160°/8

x = 20°

FINDING ALL ANGLES:

2x = 2(20°) = 40°

3x + 10° = 3(20°) +10° = 70°

Angles of the upper triangles are 40° and 70°.

HAVE A NICE DAY!!!
