Hello! The answer is .
Step-by-step explanation:
To solve this question, we have to use the Pythagorean theorem. We are given one of the legs and the hypotenuse. (The hypotenuse is opposite the right angle).
a^2 and b^2 represent our legs while c^2 represents the hypotenuse.
We have to substitute our values in for a^2 and c^2:
6^2 + b^2 = 11^2
This leaves us with 36 + b^2 = 121
To get b^2 by itself, we have to subtract 36 from both sides:
36 + b^2 = 121
-36 -36
This leaves us with b^2 = 85
To get just b, we have to take the square root:
√b^2 = √85
This leaves us with .

Answer:
The number of cases prior to the increase is 50.
Step-by-step explanation:
It is given that the number of measles cases increased by 13.6% and the number of cases after increase is 57.
We need to find the number of cases prior to the increase.
Let x be the number of cases prior to the increase.
x + 13.6% of x = 57
Divide both the sides by 1.136.
Therefore the number of cases prior to the increase is 50.
So, these are actually pretty simple once you learn the equality used to solve for "x" and when to implement this method. You can use this equality to solve for a segment "x" anytime that two secant lines cutting through a circle come from the same point outside the circle.
Secant: by geometric definition is just a straight line that cuts a curve into multiple pieces.
I did one of them for you hopefully you can use my work for "a" to help you solve for "b". For a. I got x=7.
