Answer:
Part A:
given that cos β = 3/5
that means the base line is 3 and the hypotenuse is 5
Note that, The base line 3 is adjacent to β and opposite to α.
Sin α = opposite / adjacent
sin α = 3 /5
Part B:
α and β are complementary angles
As I understand from the given above, each box when empty weighs 5-2 kg or 3 kg. To determine the total weight of Michael's boxes when empty, we just have to multiply 3 kg by 5. This gives us an answer of 15 kg. Thus, the total mass of Michael's boxes is 15 kg.

Answer:
x = 28 649/700
Step-by-step explanation:
Add 780/28.
1.07 +780/28 = x
x = 28 649/700 = 28.92_714285(repeating)
_____
If one were concerned with significant digits, one could argue that the value should be rounded to 28.93, the precision of 1.07.
