The ratio of the angle measures in a triangle is 4:5:9. What is the measure of each angle

40, 50, and 90

Step-by-step explanation:

You know that there are 180 degrees in a triangle, so you'd use the ratio to find each angle by setting up your equation like this: 4x+5x+9x=180

Then, simplify the equation and solve for x:

18x=180 x=10

Then, plug 10 into each x value to find each angle measure:

4 (10) = 40, 5 (10) = 50, 9 (10) = 90
