I think Alfred is 8 or negative -8 years old for this math problem to work
Hope this Helps
Answer:
(1 + √2)/2
Step-by-step explanation:
Assuming the values are in degrees,
sin(45) = sin(π/4)=√2/2
cos(60) = cos(π/3)=1/2
thus
sin(45) + cos(60) = √2/2 + 1/2 = (1 +√2)/2
Divide 28 by 3 and count how many are left over.
28 / 3 = 9 1/3
So each boy had 9 toy cars, and because you can't have 1/3 cars, you round 1/3 to 1. So there was 1 left over car.
