4 and 8 will equal the same since they are corresponding angles So since 8 and 7 make a line they equal 180 180= 132+"7 Subtract both sides by 132 48=angle 7
angles 1, 3, 5, 7, 9 and 11 are corresponding while angles 2, 4, 6, 8, 10 and 12 are corresponding angles 8 and 7 are supplementary since 4 and 8 are corresponding, angle 4 is 132° so angle 8 would also be 132° 180-132=48° angle 7 would be 48°
