Answer:
Step-by-step explanation:
<u>Property of regular polygons:</u>
- Sum of Interior Angles = (n−2) × 180°, where n is number of sides
<u>In our case we have:</u>
- 158.8×n = (n - 2)×180
- 180n - 158.8n = 360
- 21.2n = 360
- n = 360/21.2
- n = 17
Answer:
Step-by-step explanation:
9 * 44 =
9 (40 + 4) =
9(40) + 9(4) =

Answer:
-1/3
Step-by-step explanation:
The common difference is how much it goes up by with each new number, so you can see that each time it goes down by 1/3. This means that the common difference is -1/3.
Answer:
x=35 y=21
Step-by-step explanation:
x:y=5:3 x is in the 5 times table and y is in the 3 times table both of them added are in the 8 times table
8*<u>7</u>=56
7*5=35
7*3=21
21+35=56
