Answer:
6, 7, 2, 3
Step-by-step explanation:
supplementary means that two or more angles add together to equal 180 degrees
a straight line equals 180 degrees so the intersecting of a line creates two angles that are supplementary. That means <5 is supplementary with 6 and 7.
<5=<1 because the lines intersecting it are parrell. Using the same thinking process for angle 1 as above, it is supplementary with 2 and 3. and since 1 is equal to 5 it is also supplementary to 2 and 3.
