A decorative dinner plate is displayed in a V-shaped rack as shown. The radius of the plate is 7 inches. The measure of angle APC = 50 degrees. The sides of the rack form tangents to the plate.\r
\n" ); document.write( "\n" ); document.write( "a) Find the circumference of the plate.\r
\n" ); document.write( "\n" ); document.write( "\"c=pi%282r%29\"
\n" ); document.write( "\"c=pi%282%287%29%29\"
\n" ); document.write( "\"c=14pi\"\r
\n" ); document.write( "\n" ); document.write( "b)Find the measure of angle PAB. Explain how you found the measure.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "*This depends on the placement of B, which is not identifiable given the question alone. You probably have a diagram. If you can describe where B is located on the circle, I can help you find this angle.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "c)Find the measure of minor arc AC and major arc ADC. Explain how you found the measure \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If the center of the circle is P, then APC is a central angle. Therefore its arc, AC, is the same measure as the angle. angle APC = 50 degrees, therefore arc AC=50 degrees.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "d)Use the circumference of the circle that you found in part a to find the length of arc AC. Explain your answer.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "How much of the circumference is 50 degrees?
\n" ); document.write( "\"x%2F%2814pi%29=50%2F360\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Cross multiply:
\n" ); document.write( "\"360x=700pi\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Divide by 360
\n" ); document.write( "\"x=1.944pi\"
\n" ); document.write( "
\n" );
