3. skaterman665

heres one

4. skaterman665

and the other

5. nphuongsun93

b should be: angle 2 = angle 4 so angle 4 = 110 degree c: because angle 4 + angle 3 = straight line (180 degree) d: 180 degree - 110 degree = 70 degree

6. skaterman665

thanks!, also could you try and explain how to do it?

7. nphuongsun93

|dw:1349888366392:dw| angle 2 = angle 4 thanks to the parallel lines

8. nphuongsun93

|dw:1349888457754:dw|angle 4 + angle 3 = 180 because two angles add up to a straight line

9. nphuongsun93

then to find angle 3, take 180 degree - angle 4
