Truck is 30% less than bus
40 divided by 1.3 = 30.77
Car is 75% less than truck
30.77 divided by 1.75. = 17.58 feet
        
             
        
        
        
Answer: 101 Degrees for angle BCD
Step-by-step explanation: All 3 angles in any triangle add up to 180, in the first triangle (one on the left), you have 58 and 78 degrees, add them both and subtract from 180, you get 44 degrees for angle C on the left. Do the same on the right side of the triangle, you should get 35 degrees for angle C on the right. Add them both up, (35+44) then subtract from 180 degrees to find the measure of angle BCD.

                |       \    320 ft
                |          \
                |      54°  \
-------------+--------------+-------------------------------
                         x
cos 54° = x/(320 ft)
x = 320 ft × cos 54°
x = 188 ft
Answer: 188 ft
