<span>Each Interior Angle = <span>(<span>(Number of Sides -2) • 180 degrees<span>)<span> ÷ (Number of Sides)

Solving for number of sides
</span></span></span></span></span>
<span>Each Interior Angle / 180 = <span>(N -2) <span>/ (N)

144 / 180 = (n-2) / n

144 * n = 180n -360
360 = 36 n

n = 10 the number of sides

The first two diamonds are filled in, can you figure out how the numbers are related when
balu736 [363]

Answer:

Step-by-step explanation:

Upper box in the diamond: Add the two numbers  ⇒ (-2) + 3 = -1

Bottom box in the diamond : Multiply the two numbers ⇒ (-2) * 3 = -6

3) Upper box = (-6) +  (-3)  = (-9)

Bottom box = (-6) *(-3) = 18

4) Upper box  = 1 +(-11) = -10

 Bottom box = 1 *(-11) = -11

5) Upper box = 7+8 = 15

Bottom box = 7*8 = 56
