Answer: choice d, angle B

They couldn't match the choice letters with the angles? Geez.

10. That's an isoscles triangle

d + d + 116 = 180

2d = 64

d=32

choice a

11. 62+45+k=180

DB/dt = k*B
dB/(kB) = dt
Integrating both sides:
1/k*ln|B| = t + C
B = C*e^(kt)
At time t = 0, B = 4000 and at time t = 3 (3 hours past 9 AM), B = 4500
4000 = C
4500 = 4000*e^(3k) => k = 1/3*ln(9/8)
At time t = 15 (Midnight), B = 4000*e^(1/3*ln(9/8)*15) = 4000*(9/8)^5 = 7208 bacteria
