Check all that apply. (there are three answers) if tanθ = 15/8, then:
a. secθ = 17/8
b. cosθ = 15/17
c. cotθ = 8/15
d. cscθ = 17/15
i have no idea how to figure this out, if anyone can give a step by step explanation, that would be great! i know c is correct because cotangent is the opposite of tangent and that means that if tangent is 15/8 then the cotangent would be 8/15. but how do i figure out which of the other choices are equivalent?

Adoctor administers a drug to a 38-kg patient, using a dosage formula of 50 mg/kg/day. assume that the drug is available in a 100 mg per 5 ml suspension or in 500 mg tablets. a. how many tablets should a 38-kg patient take every four hours? b. the suspension with a drop factor of 10 ggt/ml delivers the drug intravenously to the patient over a twelve-hour period. what flow rate should be used in units of ggt/hr? a. the patient should take nothing pills every four hours. (type an integer or decimal rounded to the nearest hundredth as needed.)

Rounded to the nearest tenth, what is the value of x
