X = (0 + 8)/2 = 4
<span>y = (0 + 4)/2 = 2 </span>
<span>so midpoint is (4, 2) </span>
we solved it by using mid point formulae

Answer: 432cm^3
Step-by-step explanation:
Remember that cos is just a translation of sin and vice versa.
So:
Sin(x) = Cos(90 - x)
Cos(x) = Sin(90 - x)
Therefore, to answer your question:
Cos(19) = Sin(90 - 19)
= Sin(71)
