Answer:

x = 4

Step-by-step explanation:

(6x - 3)° = (2x + 13)° are vertical angles that equal each other get x by itself and solve for x.

(6x - 3)° = (2x + 13)°

6x - 2x = 13 + 3

4x = 16

x = 4

Substitute x for the angles.

(6x - 3)° = ?

(6*4 - 3)° = ?

(24 - 3)° = 21°

(2x + 13)° = ?

(2*4 + 13)° = ?

(8 + 13)° = 21°

If a point is chosen inside the square, what is the probability that it will also be inside the circle?
Feliz [49]

Answer:

79\%

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 s is given by A=s^2
  • Area of a circle with radius r is given by A=r^2\pi

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: A=2^2=4

Area of circle:

A=1^2\pi=\pi

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

\frac{\pi}{4}=0.78539816339\approx \boxed{79\%}
