Question

plzzzzz solvee thisss​

Answer 1

Step-by-step explanation:

given that:

angle BOC :angle AOC=2:7

TO FIND:

angle AOC and angle BOC

Answer:

consider the angles be 2x and 7x

according to the theorem ,the sum of all angles in a straight line is 180 degree.

now we gave

2x+7x=180

9x=180

x=20

angle AOC=7x=7(20)=140degree

angle BOC=2x=2(20)=40degree

Answer 2

Heya ❤

Let angle BOC be 2x and angle AOC be 7x

So, angle BOC + angle AOC = 180° (LINEAR PAIR)

=> 2x + 7x = 180°

=> 9x = 180°

=> x = 20°

Angle BOC = 7x = 7×20 = 140°

Angle AOC = 2x = 2×20 = 40°

Hope this helps you ☺
