The technique I use is add up the numbers in the ratio. You get 2 + 4 + 4 = 10. Now to find the angles, you have to find the fraction of each number in the triangle. So
. Since the other two angles are 4 and 4, which are two times of 2, we can say the other two angles are 72 degrees each.
1+3+6=10
40=10 units
diidde by 10
4=1unit
4 times 1=4
4 times 3=12
4 times 6=24
they paid $4, $12 and $24
Becouse k and n are 'neighbours' so their sum are 180
so k=180-42=138
