I need help with a few questions, if someone could do the problem and show how you did it that would be great.
Solve In Radians
2sinx -1 = o
sinx=squareroot of 3 - sinx
Angle Addition
Tan 105 degrees
Find each value of the trig function
Sin u = 3/5 cos u = 7/25
Thanks.
And the last one..... I think you mean to find the other trig ratios given the sine ratio of an angle, and given the cosine of another angle. Is that right?

Use Pythagoras to find x:
Then, fill in the remaining ratios (could be in QI or QII).
Do something similar with . Could be in QI or QIV.
