Step-by-step explanation:
The trains are separating at the rate of 80 +70 = 150 km/hour. The time required to be 50 km apart is then ...
time = distance/speed = (50 km)/(150 km/h) = 1/3 h = 20 minutes

Answer:
First we need to calculate ∠R
Since ∠R is one of three angles of ΔRDJ, we have:
∠R + ∠D + ∠J = 180°
∠R = 180° - ∠D - ∠J
∠R = 180° - 83° - 39° = 58°
Since ΔRDJ ~ ΔTRB, we can con conclude that:
∠R = ∠T
Because ∠R = 58°
=> ∠T = 58°
