Question

In the given figure, AOB is a straight line. Find xand angle AOC, BOC

Answer 1

hey frnd

here is ur answer

since both the angles lie on a straight line

there sum will be equal to 180°

so

2x+10+3x=180°

5x+10°=180°

5x=180°-10°

5x=170°

X= 170°\5

X=34°

Answer 2

In the given figure :
Angle AOC and Angle BOC are in linear pair
Hence their sum is = 180
Angle AOC = 2x + 10
Angle BOC = 3x
Now,
2x + 10 + 3x = 180
5x + 10 = 180
5x = 180 - 10
5x = 170
x =170 ÷ 5
x = 34 degree

Hope it helps.
