Hi.
First, I am going to give you some definitions.This will help you do the problems.
-Complementary angles have a combined sum of 90.
- Supplementary angles have a combined sum of 180.
10. 40+50=90- so YES.
12. 159+20= 179.-so NO.
Make sure you learn the definitions properly next time!

Answer:
Well it is 16
Step-by-step explanation:
the rectangle has 2 of the same sides for each side, so 3x2+5x2, a square has all sides equal to each other, so 4x4
So Now we do the easy part|
The rectangle that is grey:
3x2 = 6
5x2 = 10
6+10 =16
The orange square:
4x4 = 16
4+4=8
4+4=8
8+8=16
Therefore both are 16, meaning 16 must be the perimeter for both!
Answer:
-2
Step-by-step explanation:
We can set it equal to zero
2x+4 = 0
2x =-4
x = -2
12.40 am is the next time they both ring at the same time
