Answer:
60, 36, 84
Step-by-step explanation:
The angles of a triangle always add up to 180 degrees.
If the ratios are 5:3:7, that means that there are 15 pieces that we can break up the 180 degrees by.
180/15 = 12
Each value is 'worth' 12 degrees.
Thus the angles would be the ratios multiplied by 12.
5 x 12 = 60
3 x 12 = 36
7 x 12 = 84
Hope this helps! sorry if it is kind of dark
A graph that uses vertical or horizontal bars to display data is called a bar graph. It is really useful in showing comparisons between multiple data groups. Also, it can be used to track changes over time. Hope this helped!
