What is the measure of line QR to the nearest hundredth of a centimeter?http://i1100.photobucket.com/albums/g413/nivvvbappp/HS_GMT_L3_S2_05_03_quiz1.gif
According to your diagram, PQR triangle is a right angled triangle. In a right angled triangle,
`sin(49) = (QR)/(PR)`
`0.7547 = (QR)/12.38`
QR = 12.38 * 0.7547 cm
QR = 9.343186 cm.
Therefore the length of QR is 9.34 cm to the nearest hundredth of a centimeter.
this is the picture for the question;
