We have m(<CBO) = (1/2) · m(<CBE) = (1/2) · ( x + z );
In the same way, m(<BCO) = (1/2) ·( x + y);
m(<BOC) = 180 - [(1/2) · ( x + z ) + (1/2) ·( x + y)] = 180 - (1/2)· ( x + x + y + z );
But, x + y + z = 180;
Then, m(<BOC) = 180 - (1/2)·( x + 180 );
Finally, m(<BOC) = 90 - (1/2)·x;
So, m(<BOC) = 90 - (1/2)·m(<BAC).
Answer:
2x and 7y, because they have different variables.
Step-by-step explanation:
Heya !
Given expression -

Subtracting 25 both sides ,

Dividing by 3 on both sides ,

Therefore ,
(-3/1) * (1/-3) = 1
