Question

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

Answer 1

Answer:

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
