Question

In the following figure 'l' and 'm' are two lines intersected by a transversal 'p'.If angle 1 = 130° and angle 8 = 50°then, is lll m ? State reason​

Answer 1

Answer:

angle 1=130°

linear pair angle 1+ angle 2=180°

angle 2=180°-130°=50°

angle 2=50°

therefore angle 3 =130°

angle 4=50°

angle 8=50°

linear pair angle 8+ angle 7=180°

50°+angle 7=180°

angle 7=130°

therefore angle 5=130°

angle 6=50°
