Question

Ans is x =16 degree please solve this question​

Answer 1

Answer:

x = 16degree

Step-by-step explanation:

Angle AOC + Angle BOC = 180degree (Linear Pair)

3x+(7x+20) =180

10x + 20 = 180

10x = 160

x = 16 degree

Answer 2

Answer:

Sum of angles in a straight line is 180°

$3x + (7x + 20) = 180$

$3x + 7x + 20 = 180$

$10x + 20 = 180$

$10x = 180 - 20$

$10x = 160$

$x = \frac{160}{10}$

$x = 16$
