<h3>What is the triangle?</h3>A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
∠ABC + ∠BCA + ∠CAB = 180°
60° + ∠BCA + 50° = 180°
∠BCA = 180° – 110°
∠BCA = 70°
Then the correct option is C.
The complete question is given below.

Answer:
They will meet in 1.8 hours.
Step-by-step explanation:
Given that, distance between trains = 306 miles
Let they take time to meet each other.
Speed of first train = 90 mph
Speed of second train = 80 mph
Let distance traveled by first train = miles
Formula for distance:
Distance traveled by first train,
Let distance traveled by first train = miles
Formula for distance:
Distance traveled by first train,
Total distance traveled is 306 miles.
i.e.
They will meet in 1.8 hours.
