Draw an imaginary line from the vertex of angle x to the center of the circle.
This divides the 4-sided polygon into two right triangles. For example, the upper right triangle has an acute angle whose measure is 135 degrees / 2, or 67.5 degrees, and the another acute angle whose measure is x/2.
x/2 and 67.5 degrees are complementary angles, so x/2 + 67.5 deg = 90 deg. Thus, x/2 = 22.5 deg, and so x = 45 deg. (answer)

Answer:
4 Minutes = 240 seconds = 6*40 seconds
30*(1/2)^6 = 30*1/64 = 30/64 = 15/32 = 0.5
4 minutes later there is approx. 0 to 1 bacteria alive.
Answer:
Mean = 3.125 ≈ 3.13
Step-by-step explanation:
Mean = <u>Sum of numbers</u> = <u>1 + 2 + 3 + 4 + 2 + 6 + 3 + 4</u> = <u>25</u> = 3.125≈3.13
