From the contour line that is a combination of two line segments that connect but do not intersect, 500 and 750 represent elevation on the topographic map. There are 5 contour lines in between the given elevations 500 and 750, therefore, the contour interval is 50. Since the peak of the mountain is 2 contour lines from 750, the elevation of the mountain is 850. Hence, the answer is 871 meters.
