The angle measure of a straight line is 180°, and so if the you know that one angle off of it is (5x)°, then you know that the other section is (180 - 5x)°.
Because it's an isosceles triangle, there are two identical angles, which happen to be the angles with the measure of (5x - 30)° and (180 - 5x)°.
Since they have the same measure, 5x - 30 = 180 - 5x. Solve:
![5x-30=180-5x\\\\10x=210\\\\x=\frac{210}{10}=21](https://tex.z-dn.net/?f=5x-30%3D180-5x%5C%5C%5C%5C10x%3D210%5C%5C%5C%5Cx%3D%5Cfrac%7B210%7D%7B10%7D%3D21)
Thus,
x = 21°.
Answer: The answer is 14
Step-by-step explanation: So, for every 5 books she gets, she gets two free. Here is a chart
5 books bought=2 free books
10 books bough=4 free books
15 books bought=6 free books
20 books bought=8 free books
25 books bought=10 free books
30 books bought=12 free books
35 books bought=14 free books
Every five books bought equals two free books, so if she buys 35 she would get 14, so 49 books in all. hope this helps :)

Formula for Contribution Margin
1. Contribution Margin = Net Sales Revenue – Variable Costs. OR.
2. Contribution Margin = Fixed Costs + Net Income. To determine the ratio:
3. Contribution Margin Ratio = (Net Sales Revenue -Variable Costs ) / (Sales Revenue) Sample Calculation of Contribution Margin.
