Hi, this is a bit embarrassing but I'm a bit rusty with this stuff.
My first question:
a) If sin(a°) = 0.951, then what is tan a equal to?
The answer is 3.076 according to the book, however i'm not sure how this conclusion is reached? If someone could explain that'd be nice.
If 0°<a<90° and cos a<0.5, then which of the following is correct?
A. a<30° B. a>30° C. a<60°
D. a<45° E. a>60°
Once again, no idea on how to go about this and need clearing up. Do any of these questions relate to :
tan(x) = sin(x) / cos(x)
sinē(x) + cosē(x) = 1
