For 5 and 9there is no gcd except for 1 for 2 and 12 2 is the gcd
<BCD = 1/2(mAE - mDB)
<BCD = 1/2(110 - 30)
<BCD = 1/2(80)
<BCD = = 40
answer
The measure of <BCD = 40°
Answer:
t = 70 tons/1.5 tons/min = 46.7 min = 2800 sec before boat sinks
S = V * t
V = S / t = 20 mi * 5280 ft/mi / 2800 sec = 37.7 ft/sec
Since 88 ft/sec = 60 mph
the speed is 60 * 37.7 / 88 = 25.7 mph
