a) A triangle with sides of 18 cm, 33.75 cm, and 38.25 cm would be a right triangle if (and only if) the squares of the shorter sides add up to the square of the longer side.
\n" ); document.write( "Since \"18%5E2%2B33.75%5E2=324%2B1139.0625=1463.0625\" and \"38.25%5E2=1463.0625\" that triangle is a right triangle. The longest, 38.25-cm side is the hypotenuse and the other two sides are the legs of the right triangle.
\n" ); document.write( "
\n" ); document.write( "Probably the terms \"triangular prism\", \"the base of this prism\" and \"right triangular\" (prism) confuse you.
\n" ); document.write( "The problem calls the window a \"triangular prism\" to recognize that there is some thickness to it. It seems like an excess of correctness. I bet they would correctly a coin \"cylindrical\" instead of \"round.\"
\n" ); document.write( "
\n" ); document.write( "b) The measure of the angle opposite the 38.25 cm is \"90%5Eo\" or \"pi%2F2\" radians. Since we proved that the triangle is a right triangle, the longest side, measuring 38.25 cm, is the hypotenuse, which is opposite the right angle.
\n" ); document.write( "
\n" ); document.write( "c) The 33.75 cm side and the 18 cm sides are the legs of a right triangle.
\n" ); document.write( "Consequently, the tangent of the angle opposite the 33.75 cm side is the ratio of measures of opposite side, divided by adjacent side.
\n" ); document.write( "\"tan+%28angle%29=33.75%2F18=1.875\" --> \"angle=1.0808\" (in radians, rounded) or \"angle=61.93%5Eo\" (rounded)
\n" ); document.write( "
\n" ); document.write( "d) The 33.75 cm side and the 18 cm sides are the legs of a right triangle.
\n" ); document.write( "Consequently, the measures of the angles opposite those sides add up to the measure of a right angle: \"90%5Eo\", or \"pi%2F2\" radians.
\n" ); document.write( "Then the measure of the angle opposite the 18 cm side is
\n" ); document.write( "\"90%5Eo-61.93%5Eo=28.07%5Eo%7D%7D+or+%7B%7B%7Bpi%2F2-1.0808=0.4900\" radians (rounded)
\n" ); document.write( "
\n" );
