**Trigonometry**

•Trigonometry - Bosnian, Sunday, September 9, 2012 at 1:07am Area of right triangle = 1 / 2 Area of a rectangle In this case: A1 = ( 1 / 2 ) * 8 * 15 = 60 units When each side is doubled: A2 = ( 1 / 2 ) * 2 * 8 * 2 * 15 = 4 * ( 1 / 2 ) * 8 * 15 = 4 A1 A2 = 4 * 60 = 240 units

**trigonometry**

Do you have a calculator? I assume that the log you are talking about is base 10. log(47) = 1.672 log(w) = -2.866 + (2.722)(1.672) = 1.6855 w = 10^1.6855 = 48.5 lb This subject is not trigonometry. It is logarithms. You need a scientific/math hand calculator or a computer to ...
