Question

in the given figure AOB is a straight line and the ray oc stands on it if AOC =(2x-10)degree and BOC =(4x+10) find the value of x also find AOC and BOC ​

Answer 1

Answer:

Given, angle AOC = (2x - 10°) and angle BOC = (3x + 20°) also, AOB is a straight line. The sum of two angles on a straight line is 180° . => x = 34 Answer.

Answer 2

$2x - 10 = 4x + 10$

$2x - 4x = 10 + 10$

$- 2x = 20$

$x = \frac{20}{ - 2}$

$x = - 10$

$put \: value \: of \: x \: \: in \: above \: equation \:$

$2( - 10) - 10$

$- 20 - 10 = - 30$
