Two cars started out 75 miles apart on straight highway, traveling towards each other at a constant speed. One hour later, the two cars passed each other. If they stayed at their speeds and directions, how far apart were they an hour after they met ?

b. astronomers

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
