In the diagram below, start overline, O, P, end overline OP is parallel to start overline, L, M, end overline LM . If M, P, equals, 16MP=16, O, P, equals, 15OP=15, and L, M, equals, 27LM=27, find the length of start overline, N, P, end overline NP . Figures are not necessarily drawn to scale. State your answer in simplest radical form, if necessary
