Question

In thw above figure find <x.Further find <BOC,<COD and <AOD​

Answer 1

Answer:

Use of Linear pair again!

So, x + x+10+ x+20 = 180

--> 3x + 30 = 180

--> 3x = 180 - 30

--> 3x = 150

--> x = 150/3 = 50⁰

So, x = 50⁰

Answer 2

Answer:

x = 50°

Angle BOC = 70°

Angle COD = 50°

Angle AOD = 60°

Step-by-step explanation:

(x+10) + x + (x+20) = 180 (Angles on a straight line = 180)

3x + 30 = 180

3x = 180 - 30 = 150

x = 150/3 = 50°

x = 50°

Angle BOC = x + 20 = 50 + 20 = 70°

Angle BOC = 70°

Angle COD = x = 50°

Angle COD = 50°

Angle AOD = x + 10 = 50 + 10 = 60°

Angle AOD = 60°

Hope it helps you:)
