Have a nice day.

Hope that u are fine .

Here is ur answer.

Hope this will help you.

Plz mark me as the brainliest.

Step-by-step explanation:

Angle C = angle A( interior opposite angles ) 

angle A = 2x

by angle sum property of a triangle 

2x + 3x + 10 = 180 

5x = 180 - 10 = 170 

5x = 170 

x = 35 

2x = 2 * 35 = 70 

3x + 10 = ( 3*35 ) +10 = 115 

hope it helps you

Answer 2

Answer:

20°

Step-by-step explanation:

since AB=AO. (given)

=>angle AOB= angleABO = 3x+10.....(1)

since OC= CD. (given)

=> angleCDO = angle COD= 3x+10....(2)

[ from eqn (1) since AOB= COD]

in triangle COD

=> < C+< O + < D= 180

=> 2x+(3x+10)+(3x+10)= 180......from (2)

=> 8x+20= 180

=> 8x= 160

=> x= 20° answer
