Answer:
Because it can be shaped to make things magnified
The angle of B is 56.2 degrees
<em><u>Solution:</u></em>
Given is a right angled triangle ABC
From given figure,
AB = 9
CB = 5
We have to find the angle of B
Let the angle of B be 
By definition of cosine,

Here, adjacent = CB and hypotenuse = AB
Therefore,

Taking cos inverse on both sides,

Thus the angle of B is 56.22 degrees
The nearest whole number would be 1!
Answer: 13 hours
Step-by-step explanation:
The scenario that is being described can be fully made into an equation using three variables. These would be w for the number of weeks, b for the number of hours she babysat that week, and x for the total amount of hours worked. Like so...
5w + t = x
Since we are told that we need to find the total hours worked for a single week (w = 1) and that Erica babysat for 8 hours that week (b = 8), then we only need to solve for the total amount of hours worked (x)
5(1) + 8 = x
5+8 = x
13 = x
Erica worked a total of 13 hours.
