area of a circle = πr², where r = the radius of the circle
We can rearrange the formula to solve for r:
Given an area of 1017.36 in² and using 3.14 for our value for π, the radius of our circle would be:
<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

Answer: Angle 2: 45°
Step-by-step explanation:
All triangles add up to 180, so all you would so is take both of those angles and subtract them from 180, so basically 180 - 135
Marguerite is going to need 4 pieces of wood because...
1 piece= 6m which =600cm
She needs 78 pieces of 29cm78x29=2262
then divide 2262 by 600 and that gives you 3.77.
You cant have 3.77 pieces of wood so you have to round to 4.
