I need to prove m>3 = 70 degrees

anonymous · Answer

this is given

isaidavila · Answer

Since angle 2 in equal to 4, and the sum of the angle in a rect line is 180
So 3+4=180
3+110=180
3=???

btaylor · Answer

If m<2 = m<4, then m<4 is 110 degrees. 
Then you can use supplemental angles to find m<3

anonymous · Answer

m<4 = 110 degrees. What rule would that be?

anonymous · Answer

m<2 = m<4 that is definition of congruent angles. So what would M<4 = 110 degrees be? @BTaylor

isaidavila · Answer

What

isaidavila · Answer

M2 = m4 because their are congruent 
110=m4

anonymous · Answer

So would it be reflexive property?

anonymous · Answer

This is the problem if it helps I'm trying to get better understanding of this and how to figure out the properties

mathstudent55 · Answer

Above, you already have these steps.
Now you can star dealing with supplementary angles.
