Ответ:
Complementary means equal to 90 degrees.
Supplementary means equal to 180 degrees.
Choice #1 is correct because the angles have to be equal to 90 degrees, and in the picture you can see that those two together are a right angle, which is 90 degrees.
Choice #2 is incorrect because on the picture it is obviously less than 180 degrees.
Choice #3 is correct (same reason #1 is correct)
Choice #4 is correct because we can see that HNL is a straight line, which is equal to 180, and the angles add up toe the line HNL.
Choice #5 is incorrect because MNG was already a 90 degree angle, so adding another angle would not make it a right angle again.
I hope this helps!!
