In the attached diagram, write, for the upper triangle:

tan 37 degrees = x/10

In the attached diagram, write, for the lower triangle:

tan 45 = y/10

You should be able to finish up.

Note:  

1. Sending several questions at the same time suggests you are using the site improperly -- either asking us to teach you the subject or to do your homework for you.  Both are improper.

2. Sending three individual questions at the same time is definitely abusive.  It uses up my quota and blocks others.  I suspect you would have sent more, but my quota is 3.

Please use the site responsibly.
