Question

One angle of a triangle measures 100°. the other two angles are in a ratio of 3:5. what are the measures of those two angles?\

Answer 1

Sum of those two angles = 180 - 100 = 80
Now, Total ratio = 3 + 5 = 8
Amount of 1 unit = 80 / 8 = 10
Angle measures: = 3(10) & 5(10) = 30, 50

In short, Your Answer would be 30 & 50

Hope this helps!
