Answer:
The answer is C. 30
Step-by-step explanation:
First, you would do 36 divided by 6 to get 6. Then you do 5 times 6 to get 30. You have to multiply both five and six by 6 to get an equal ratio.
5:6 is equal to 30:36.
Assuming a and b are parallel
<5 = <9 false
<1 = <12 false
<1 = <8 true
<3 = <7 true
Answer: 15
Step-by-step explanation: Perimeter is adding the width and the length together. For a rectangle, it has four sides, so it has two lengths and two widths. The width is 10, so you add 10 + 10 which is 20. The length of the rectangle would be 15 since 15 + 15 is 30, and then 30 + 20 = 50, the perimeter.
