The answer is C because an angle is determined by the letter in the middle. It is given that a is smaller than b and c=90
Answer:
I hope this helps. This is what a number line looks like and how you do it.
I will only be writing the reasons for each and you can respond if you need clarification for anything:
1. given
2. opposite sides of a parallelogram are congruent (and a rectangle is a parallelogram so the properties apply)
3. def rectangle
4. SAS (side angle side congruence theorem)
5. CPCTC (congruent parts of congruent triangles are congruent)
If 1=16, 3=48. 3 is displayed twice so 48+48+16=112
Ans. 112
Complementary means sum = 90, so 90-57 to get the other angle at 23 degrees
Supplementary means sum = 180, so 180-52 to get the other angle at 128 degrees
