The only disadvantage I could think of would be price of equipment needed to produce energy from the source (i.e. price of solar panels)
Answer:
We know that sin(x) = cos(90°-x). In that sense, we know that:
sin(25°) = cos(90°-25°) = cos(65°)
If you put both values in a calculator, we get that:
sin(25°) = 0.4226
cos(65°) = 0.4226
Therefore: Sin 25° = Cos 65°
He claimed that they were one large supercontinent called Pangaea. His evidence for his claim was that the general shapes of the separate continents and how they can fit together if you arrange them. He noticed patterns in the mountain ranges; when all the continents are together the ranges line up with one another.
