All triangles have sides, but right triangles and isosceles triangles have legs.
\n" ); document.write( "The legs of a right triangle are the sides that are at right angles to each other.
\n" ); document.write( "Trigonometric ratios (sine, cosine, tangent) are defined based on the measures of the sides of a right triangle.
\n" ); document.write( "The tangent of an angle is
\n" ); document.write( "tangent = opposite side/adjacent side.
\n" ); document.write( "The smaller angle, is the one opposite the leg measuring 146, and its tangent is
\n" ); document.write( " $\"146%2F186=about0.785\"$ (rounding)
\n" ); document.write( " $\"tan%5E-1%280.785%29=about38.1%5Eo\"$ (rounding)
\n" ); document.write( "The measure of the other angle would be $\"90%5Eo-38.1%5Eo=51.9%5Eo\"$
