ABCD is a parallelogram. If mZCDA = 75, then what is mZDAB?
1 answer:
Answer:
Therefore
m∠ DAB is 105°
Step-by-step explanation:
Given:
ABCD is a parallelogram. The diagram is not drawn to scale.
m∠CDA = 75°,
To FInd
m∠DAB = ?
Solution:
ABCD is a parallelogram.
AB || CD .......{opposite sides of a parallelogram are parallel}
∴∠CDA+∠DAB = 180°{SUM of the interior angles between parallel are supplementary}
substituting the values we get
Therefore
m∠ DAB is 105°

Here speed of first train is slower than speed of second train. So if they catch up , the distance traveled will be same since they left the same station at different times.
But the time traveled will be different .
Let us say the two trains meet at time t ,
Distance = speed * time
Distance traveled by first train = 40 t
Since second train is leaving after three hours , so
Distance traveled by second train = 60(t-3)
As discussed earlier, distance traveled will be same, so
distributing 60 over t-3
t=9
So the second train will meet the first at 9 p.m.
