The answer would be 50 divided into 360 and then divide to find your answer and you can explain by saying how you divided to get your total
Each pound 4.20/2 = $2.10
5 pounds will cost + 2.10 x 5 = $10.50
the value of x always equals zero
Complement angles mean that the sum of them = 90°
Say one if them = X
then the 2nd will be 5X
X+5X =90°
6X = 90°
X = 90/6
X = 15°
Therefore,
the 1st angle X = 15°
the 2nd angle 5X = 15 ×5 = 75°
