I'm in summerschool right now and in regular school the teachers never taught us about trigonometry, yet i got 2 trigonomical questions thrown at me by my summerschool proffesor. I have ABSOLUTLEY no clue of what i am supposed to do.

The first problem:

I am to find out which of the four alternatives below is the same as 267^{o}, I believe several alternatives might be the awnser but i am not entirely sure:

1. 1347^{o }2. 329*pi/60

3. -993^{o}

4. -91*pi/60

What i was able to do was transform the 267^{o}to radians, 89*pi/60. After that i tried all the formulas for both degrees and radians and nothing worked.

The second problem:I am to find the distance between the point (-5, 7) and the point were this line: -8x+4y=16 intercepts the x-axis.

The awnser is supposed to be $\displaystyle sqrt$awhereaisawhole number.

I have tried the distance formula on this many times and failed, i could really use some help!
