Homework Help: Algebra

Posted by Casey on Tuesday, April 1, 2008 at 6:07pm.

Suppose a triangle has angles A,B, and C. Angle C is the right angle. Find the measures of the other sides to the nearest whole number.


< means angle symbol.



1.BC=9,m<B=72 degrees
I got angle AB=28 and angle AC=29

To solve these problems you find either the sine, cosine, or tangent of the equation. Afterwards you just cross multiply. Well, when I went to check my work, the answers were flip flopped(AC=28 and AB=29). Can someone check my work to make sure I am right.
