Question 402663: My directions: The measure of the angles of a triangle are in the ratio 5:6:9:. What is the measure of each angle? I missed the lesson so I am confused at where to begin. Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! The ratios are 5:6:9
The total parts will be 5+6+9=20
..
The sum of angles of triangle = 180 deg.
..
the first angle is 5/20 * 180 =45 deg
The second angle = 6/20*180=54 deg
The third angle = 9/20*180=81 deg.
...
CHECK
45+54+81= 180
Divide by 9
5:6:9
