Ineed , i don’t understand how to do this

ANSWER:

                 m∠1 = 60°

                 m∠2 = 60°

                 m∠3= 120°

EXPLANATION:

The purple arrows indicate that side are parallel, so we know that that triangle NMP is the same as triangle NOP. If they are they same then we know that ∠1 and ∠2 equal 60° since the opposing angles equal 60°.

For ∠3 we look at the opposing angle and now know it is 60°. Since ∠3 and the opposing angle make a straight line which equals 180°. We can figure out ∠3 by subtracting 60 from 180 = 120°.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
