ganeshie8 · Answer

is it given that the line l and m are parallel ?

ganeshie8 · Answer

if so, angles 1 and 5 will be supplementary

ganeshie8 · Answer

do u know what supplementary angles are ?

anonymous · Answer

uhhhhh no i dont

ganeshie8 · Answer

supplementary angles are the angles that add up to 180

ganeshie8 · Answer

since 1 and 5 are supplementary angles, they should add up to 180 :

m1 + m5  = 180

120 + m5 = 180

m5  = 180 - 120
       =  ?
