Mapping Mars 10.1 & 10.2 Mars Rover "Curiosity" has been transmitting measurements of the Gale Crater. Unfortunately, the rover has been encountering some unknown difficulties and only certain measurements have been received, as shown in the map on the next slide. The next rover NASA will send to Mars in 2020 will carry instruments to conduct investigations in this area and will need the following measurements: * Length of DE, EF and DF (nearest tenth of a foot) Measure of the angle formed by DEF (nearest degree)\fA Fill in the missing work in the following. $48 B 186 1) Find DE, to the nearest tenth of a foot. E DE sin sin 80 D DE = All Rights Reserved @ MathBits.com 2) Find EF, to the nearest tenth of a foot. C Mars Rover Mapping of the Gale Crater EF 2 - 2 cos 250 EF = 3) Find DF, to the nearest tenth of a foot.

Complete the missing information, you will need to use your previous results. 12 + ( 0] ) 2 - 20 0 cos(m._DEF) MZDEF = COS -1 -20 A MZDEF ~ 148 B 186' E 172 D F All Rights Reserved @ MathBits.com C Mars Rover Mapping of the Gale Crater
