Lines l and m are parallel.<br> Use the diagram to determine the measure of ∠3.
Pavlova-9 [17]

Answer:

∠3 is 70°

∠1 is 50° since it is across from another 50° angle

and then you use the equation x+25+2x+50=180 to find x

x then equals 35°

you then use the alternate interior angle theorem to say that ∠3 is 2x, or 70°
