Question

Find x and all the angles .

Answer 1

$\Huge{\red{\underline{\textsf{ANSWER}}}}$

★ Sum of all the angles would be 180° ( straight line angles )

Here ,

= = 180°

= x + 10 + x + x + 20 = 180°

= 3x + 30 = 180°

= 3x = 180° - 30°

= 3x = 150°

= x = 150°/3

= x = 50°

X = 50°

∠ AOD = x + 10 = 50 + 10 = 60°

∠ DOC = x = 50°

∠ COB = x + 20 = 50 + 20 = 70°

Answer 2

$\huge{\red{\boxed{\blue{\boxed{\pink{Answer}}}}}}$

➡️✨✨Here ,

= = 180°

= x + 10 + x + x + 20 = 180°

= 3x + 30 = 180°

= 3x = 180° - 30°

= 3x = 150°

= x = 150°/3

= x = 50°

X = 50°

∠ AOD = x + 10 = 50 + 10 = 60°

∠ DOC = x = 50°

∠ COB = x + 20 = 50 + 20 = 70°✨✨
