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:

The rate of change is 2om per hour
Answer:
15
Step-by-step explanation:
50 * .30=15
Answer:
x + 3y = -12
Step-by-step explanation:
y = mx + b
m is the slope = rise / run:
rise = 1
run = 3
the line is downhill so its negative
m = - 1 / 3
b is the y intercept which is when the line cross over the y axis: - 4
y = - 1/3x - 4
multiply both sides by 3
3y = -1x - 12
add x to both sides
x + 3y = -12
