180-129= 51
angle 4 is equal to angle 12 so missing angle 12= 51°
I believe the answer would be 3/40
It could be a linear graph with a negative slope
x axis is height above ground and y axis id air pressure
so there willbe a point at (0,14.7) on y axis representing the pressure at sea level. There will be another point at (3.6, 7.35) where air pressure is half that at ground level. The straight line will continue until it reaches the x axis ad (0, 7.2) where there is no air pressure.

The total time taken for round trip will be: (f+g)(x) = 14x+11
Step-by-step explanation:
Given

In order to find the round-trip time, we have to add both functions to represent the time taken to travel east and the time taken to travel to west.

Hence,
The total time taken for round trip will be: (f+g)(x) = 14x+11
