Answer:
Felsic magma
Explanation:
Felsic magmas are higher in silica. The higher the amount of silica in the magma, the more viscous it is. Viscosity determines what the magma will do. Most felsic magma will stay deeper in the crust and will cool to form rocks such as granite. If felsic magma rises into a magma chamber, it may be too viscous to move and so it gets stuck. Dissolved gases become trapped by thick magma and the magma chamber begins to build pressure and felsic magmas will erupt explosively.
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°
