Answer:
express the followibg as a fraction and a rational number 10 to 12
suppose 4:4:7 be 4x, 4x, 7x
or, 15x = 180°
or, X = 180/15
or, X = 12
therefore,
4x = 4x12= 48
4x= 4x12= 48
7x= 7x12= 84
so if you plus all of them you get 180
The longest two sides will be 4 each and the shortest two sides will be 2 each
