Answer:
17.3
Step-by-step explanation:
To solve this equation, you need to use the pythagorean theorem which is:

a= length
b= height
c= hypotenuse
First, substitute in your values for the equation:

Then, use the squares in the equation:

Then, subtract 100 from both sides to isolate b:

Finally, square root both sides to get your answer:

Then round to the nearest tenth which gives you 17.3.
In both cases, we can use a rule of three.
<h2>First part</h2>

Therefore, 4 students correspond to 20% of 20 students in total.
<h2>Second part</h2>

Therefore, 2 doctors correspond to 8% of 25 doctors in total.
