Answer:
She earns 5.5 dollars per hour at the library
Step-by-step explanation:
I am going to assume that the questions is "how much she earns per hour at the library?"
Let's call x the amount of dollars earn by hour at the library. We know that she worked for 6 hours, thus she made 6x dollars.
Later her grandma gave her 20 dollars and she has now 53 dollars.
Let's write the equation and solve it
Amount earned + Amount given by her grandma = 53

Thus, based on this information we would have that Kia earns 5.5 dollars per hour.

The sum of all interior angles in a polygon is
180(n - 2), where n = the number of sides in the polygon.
now, notice this figure above, it has 5 sides, namely is a PENTAgon, so the sum of all its interior angles is 180( 5 - 2), or 540, therefore
Answer:
2) 6
4) 9
Step-by-step explanation:
Triangle has 3 angles, A, B, C. The total interior angle of a triangle is 180.
180 = A + B + C
180 = 72 + B + 113
180 = B + 185
B = 180 - 185
B = -5
This only proves that the figure is not a triangle because angle B is negative.
