Find the slope of line passing through {-7,-6} and {5, -6}

slope=(y2-y1)/(x2-x1)

where (x1,y1)=(-7,-6)

(X2,y2)=(5,-6)

slope=(-6+6)/(5+7)=0

1/2(2*4)=6 $$- agahajakanajak

if i'm not wrong, i would say that the third angle has (72) because the three sides of all triangles have 180 degrees and if we subtract 180 - 62 - 40 = (72) / but i'm not sure about 40 yd.
