Question

7. In the given figure, AOB is a straight line and the ray OC stands on
IF ZAOC = (2x -10] and ZBOC = (3x + 20. find the value of x.
Also find ZAOC and BOC
c​

Answer 1

Answer:

all angles of a triangle is 180 so

2x -10 + 3x +20 = 180

5x +10 = 180

5x = 170

x = 170/5

x =34

so angle AOC = 2×34 -10 = 58

and angle BOC = 3× 34 + 20 = 122

hope it helped you ☺️
