Solving for a variable in an equation means, we are changing the subject of formula of the equation.
The equation of r is: 
The equation is given as:
We start by multiplying both sides by 3
Rewrite as:
Divide both sides by 
Cancel out common factors
Take square roots of both sides
Evaluate the right-hand sides
Make r the subject
Hence, the resulting equating for r is:

Answer:
C
Step-by-step explanation:
so m is less than o and m is less than n so that means m is the shortest angle (look at the picture) as you see NO is the longest side since theres only one answer that has NO as the first choice it has to be that one.

Answer:
Step-by-step explanation:
One of the most important things to understand about lines is the definition of slope. Slope is the 'steepness' of the line, also commonly known as rise over run. We can calculate slope by dividing the change in the y-value between two points over the change in the x-value.
