The answer is c because of the fact that if the 2 angles at 55 and 20 that means that you have to add them together and get to 180 for the triangle to be true
Answer:
87.2º
Step-by-step explanation:
Complimentary angles total 90º
c + 2.8 = 90
c = 90 - 2.8
c = 87.2º
Answer: 0
Step-by-step explanation:
To find slope, I found that an easy way is the equation y2 - y1 over (divided by) x2 - x1
so for this, it would be:

which is 0/7
0 divided by 7 is 0, so there is your answer
Madison worked for 7.5 hours before school and 15 hours after school
<em><u>Solution:</u></em>
Given that, Madison works a job before and after school
Amount earned before school = $ 11.50 per hour
Amount earned after school = $ 11.75 per hour
Amount earned last week = $ 262.50
Let "x" be the hours worked before school
Given that, she worked twice as many hours after school
So, number of hours worked after school = 2x
Therefore, we can say,
Total amount earned = (Amount earned before school)(number of hours) + (Amount earned after school)(number of hours)

Number of hours worked after school = 2x = 2(7.5) = 15
Thus Madison worked for 7.5 hours before school and 15 hours after school
