Answer:
54°
Step-by-step explanation:
Your triangle is isosceles. You have been given the third angle, and you have been asked to find the measure of one of the two equal angles. We know that the internal angles of a triangle sum to 180, so 
I don't know what the spaces are meant for but I think that means 934 and 6814 only. Another point is, speed should be expressed in units of distance over time. So that would be miles/min.
So, distance could be calculated by multiplying speed and time.
d = 934 mi/min * 6814 min
d = 6,364,276 miles
This does not appear to make sense, could you perhaps add signs such as multiplication, division, etc.

1 and 2 i can't answer without proper data.
3. x+2x+2x+6 = 86
5x+6 = 86
-6 -6
5x = 80
x = 16
Side one: x is 16
Side two: 2x is 2(16) = 32
Side three: 2x+6 is 38
