Step two shows the step where he applied the distributive property.
This is because he distributed the terms in the first bracket with the terms in the second bracket
To solve this problem you must apply the proccedure shown below:
1. You have that the ratio of the measures of the three angles is 
2. The sum of the interior angle of a triangle is 
3. Let's say that the measure of each angle is
multiplied by the ratio. Therefore, you can write the following equation and solve for
:

4. Therefore, the measure of each angle is:

The answer is: 
Answer:
1/2
Step-by-step explanation:
A circle equation is (x – h)^2<span> + (y – k)^</span>2<span> = r^</span><span>2 where (h,k) is the center and r is the radius. Now all we have to do is plug in the variables.
Since (h,k)=(5,4) and r= 6
The answer would be C.
