If m angle ECD is six less than five times m angle BCE, and mangle BCD = 162º. find each
Usimov [2.4K]

Answer:

see explanation

Step-by-step explanation:

let ∠BCE = x then ∠ECD = 5x - 6 and

∠BCE + ∠ECD = ∠BCD, substitute values

x + 5x - 6 = 162, that is

6x - 6 = 162 ( add 6 to both sides )

6x = 168 ( divide both sides by 6 )

x = 28

Hence

∠BCE = x = 28°

∠ECD = 5x - 6 = (5 × 28) - 6 = 140 - 6 = 134°

a vehicle moving at a constant speed travels 45 miles in 3/4 hour. the driver thinks he will be late to a meeting that is still
Sedaia [141]
1) we calculte the driver´s unit rate of speed.
s=speed
d=distance
t=time.

s=d/t


45 miles------------------3/4 hour
x-----------------------------  1 hour

x=(45 miles * 1 hour) / (3/4 hour)=60 miles.

speed or rate=60 miles / 1 hour.

2)we calculate the distance traveled at 1.25 hour.

distance=rate * time

distance=(60 miles /1 hour) * 1.25 hour=75 miles.

Answer: the driver would´t go late, because, the distance is 65 miles, and he can travel 75 miles if he drive with that speed .
