JL is a common tangent to circles M and K at point J. If angle MLK measures 61ᵒ, what is the length of radius MJ? Round to the n
Dvinal [7]
In the problem of insufficient data quantities. I can get a general  solution.We know that tangent to a circle is perpendicular to the radius at the point of tangency. It's mean that triangles LJM and LJK are rights.

Let angle JLK like X.

So, angle JLM=61-x.

And it's mean that by using right triangle trigonometry 

Radius MJ = LM*cos(61-X)

What ethical issues have been raised by the scientific community's commitment to ensuring that experimental treatments are not
e-lub [12.9K]

Answer:

They include;

1. Fewer chances of determining how effective the treatment plan would be.

2. Inability of every patient to access the experimental treatment.

3. Difficulties in making knowledgeable decisions on the treatment plan.

4. Determining that the experimental treatments are offered with the right motive.

Step-by-step explanation:

In medical treatment administration, it is standard practice that drugs undergo clinical trials on test animals before they are administered to patients. However, some sicknesses are without known drugs for treatment or may have drugs that are still undergoing experiments and trials. In such cases, patients may want to be treated with experimental drugs.

Ethical issues such as the above-listed can arise from this. The foremost of them all is the fact that the treatment might prove ineffective thus causing more problems to the patient.
