Answer:
78.53
Step-by-step explanation:
x
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.

Trigonometry can be used to find angles and sides of simple triangles. If an 18-foot ladder touches a building 14 feet up the wall then the angle can be deduced by trigonometry. In this case, the ladder defines the hypotenuse (H) of the triangle and the wall defines the opposite (O) side of the triangle. Therefore we can use the equation theta=sin^-1(O/H) . This yields an angle of 51 degrees.
