Answer:
for the first 2 neither one is a polygon because a polygon has straight sides and is closed connections were the first shape has an open connection and the second shape has a curved line. for question i believe is 48 and question 4 is 145.
explanation.
for the last 2 problems their total equal 360 so you just add up all the side then subtract the number you got by 360 and that's your answer. ex.) 120 +130+ 62=312. 360-312=48
Hello There!
I believe that the relationships that can help you solve this problem are that the angle is Complementary and Supplementary. It is complementary because within the angle, there is an angle that is 90°. It is also supplementary because the angle itself is 180° making the angle supplementary.
I hope this helps!

Answer:
The side length is multiplied by 6.
Step-by-step explanation:
The area of a square is A = s². Suppose the side is 8 inches. This means the area is A = 8² = 64.
If you were to multiply by 36, then it becomes 64*36 = 2,304. Since squaring gave the area, it's side length would be found using the reverse operation a square root. Take the square root of 2,304.
√2304 = 48
The side length changed from 8 to 48 which is a scale factor of 6. This means 8 * 6 = 48.
