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°
Desert streams has more flash floods than the ones in humid locations. In other words, desert streams only get their water from rain.
