**Reiny**, Thursday, February 2, 2012 at 7:46amBasic application of your simple right-angled triangle properties ....

AC/25 =sin25°

AB = 25sin25 = 10.57

BC/25 = cos25°

BC = 22.66

BTW, the usual convention is to label the vertices of the triangle using capitals and label the side opposite a vertex with the corresponding small letter.

e.g. For triangle ABC

C = 90° , B = 25° and c=25
