Answer:
the answer is 108
Step-by-step explanation:
Let the slower train's velocity be x-21
Let the faster train's velocity be x
We know that the approach speed is the sum of both speeds, so x+x -21= 2x-21.
The approach rate is given by Distance/time = 471/3 = 157mpH
x+x-21=157
2x=157+21
2x=178
x=89mph
The slower train is travelling 89-21 = 68mph
The faster train is travelling 89mph.

Answer:
I got one
Step-by-step explanation:
C.converse of the corresponding angles postulate
∠1 = 58° ( alternate angles )
HOPE THIS HELPS:)
STAY SAFE
∠1 and ∠2 form a straight angle and are supplementary, thus
∠2 = 180° - 58° = 122°
