The sum of all angles (around the black dot) is 360°
All 5 angles (if you forget the red line) are the same; so each angle is 360°/5 = 72°
So Angle 1 is 72°
Answer:
Step-by-step explanation:
The answer is A. 16+10+20= 46
Answer:

Step-by-step explanation:
The probability that the point is chosen in the circle is equal to the area of the circle divided by the area of the square.
Formulas used:
- Area of a square with side length
is given by
- Area of a circle with radius
is given by
The segment marked as 1 represents not only the radius of the circle, but also half the side length of the square. Therefore, the side length of the square is 2, and we have:
Area of square: 
Area of circle:

Therefore, the probability that the point will be inside the circle is:

It would be d. none of the above
this would mean $360 earned in 30 hours
