Question

In the adjoining figure, what value of m will make AOB a straight line? Please Answer

Answer 1

Answer:

As we know that straight line = 180 °

So, we make a linear equation

(3m+5)° + (2m-25)°= 180°

(5m - 20)= 180°

5m = 180° + 20°

5m = 200°

m=40°

hence,

Angle AOC = 3m+5= 3*40+5

= 125°

Angle BOC = 2m-25= 2*40-25

= 55°
