Answer:
120 for oxen, 80 for cows, 60 for calves
o = 2x
Step-by-step explanation:
3o + 4x + 6c = 260
x = 2c
o = 2x
6x + 4x + 3x = 260
13x = 260
260 / 13 = 20
3o = 6x = 120
4x = 80
6c = 3x = 60
o = 2x
So the ratios are 4 to 5 to 5 to 8 to 9 to 9
that means that the first 2 sides can be simplified to 4 to 5
therefor the whle sum is all the units added up
4+5+5+8+9+9=40
720=40 units
divide by 40
18=1 unit
solve for each unit
we have
4 units
5 units
8 units
9 units
4 times 18=72
5 times 18=90
8 times 18=144
9 times 18=152
the angles are
72,90,90,144,152,152
