1. Find all angles, 0≤θ<360, that satisfy the equation below, to the nearest 10th of a degree.
2cos^2θ−cosθ=0
2. Find all angles, 0≤θ<360, that satisfy the equation below, to the nearest 10th of a degree.
8sinxcosx=−5cosx
3. Assume that θ is a positive acute angle.
Given: cosθ= 12/37
Find: cos2θ
4. For positive acute angles A and B, it is known that tanA= 15/8 and cosB= 12/13. Find the value of cos(A+B) in simplest form.
5. If cos B= 1/2, then what is the positive value of sin1/2B, in simplest radical form with a rational denominator?
6. Two forces of 630 newtons and 170 newtons act simultaneously on an object. The resultant forms an angle of 59 with the 170-newton force. Find the angle formed between the two original forces, to the nearest degree.
