If EF is not parallel to DG, what is mZF? 39° mZF = %3D

Q5: As a hot-air balloon began to rise, the ground crew drove 1.2 miles to an observation station. The initial observation from the station estimated the angle between the ground and the line of sight to the balloon to be 30°. Calculate distance "h" and "x" given in the diagram below. h 1.2 mi 30%

In ANOP, o = 48 inches, p = 19 inches and ZN=54°. Find ZP, to the nearest degree %3D

3. Find two elevation angles that will enable a shell, fired from ground level with a muzzle speed of 800 ft/sec, to hit a ground-level target 10,000 feet away. Write your final answers in degrees. (Ignore air resistance and use g 32 ft/sec?.)
