Answer:
12.56
The circumstances of a circle can be found by multiplying pi by the diameter of the circle. If a circle has diameter of 4, its circumference is 3.14*4= 12.56. If you know the radius, the diameter is twice as large.
One side of triangle is given equilateral triangle which means all the angles of the triangle is 60°
so we have angles of bigger triangle:-
- 60°
- 60+35= 95°
- x( to find )
<h3>Use angle sum property </h3>
( sum of all interior angles is 180°)
![x + 60 + 95 = 180 \\ x = 180 - 60 - 95 \\ x = 120 - 95 \\ x = 25 \degree](https://tex.z-dn.net/?f=x%20%2B%2060%20%2B%2095%20%3D%20180%20%5C%5C%20x%20%3D%20180%20-%2060%20-%2095%20%5C%5C%20x%20%3D%20120%20-%2095%20%5C%5C%20x%20%3D%2025%20%5Cdegree)
First, divide each amount by the downloads.
6.25/5 = 1.25 for each download
17.40/12 = 1.45 for each download
The online music store that offers 5 downloads for 6.25 is the better deal by 0.20 cents.
hope this helps
