Let us first find the angle adjacent to θ. To find this we can construct a right triangle by drawing a line segment from the point (-12,5) straight down to the x-axis. Using right triangle trig...

tan(adjacent angle)=5/12

adjacent angle=22.62 degrees

Since the two angles make a linear pair.

θ=180-22.62=157.38 degrees

Ymorist [56]

Convert the dose into mg / lb

1 lb = .45 Kg

so the does = 6 * .45 = 2.7 mg/lb

so the daily dose of the patient is 93 * 2.7 = 251.1 mg

injections are available in 50mg per mL

to calculate the daily dose in mL 251.1 / 50 = 5 mL
