13. To find the distance RS across a lake, a surveyor creates a right triangle, RST, and
measures the length of RT to be 61.8 meters. If the measure of angle T is 37.4°, what
is the length RS of the lake? Write an equation, solve it and round your answer to the
nearest hundredth. Include units in your answer for full credit.
