Answer is 50 degrees
Since,
measure of angle F + measure of angle G + measure of angle H = 180
30 + 100 + measure of angle F = 180
Measure of angle F = 180 - 130
Measure of angle F = 50 degrees
3x2+4x=2
6+4x=2
-6 -6
4x=-4
4 4
x=-1
To find the slope, use the equation of a line: 
Plug in the values for x and y:
We know that 2 can fit into 5 twice, which means 2*2 is 4.
We now have 
.
If 5 is b more than 4, then this means that 4 is b less than 5. Subtract 4 from both sides, and you will have b = 1.
This means your equation is y = 2x + 1.
Let x be the distance between the plane and the airport.
We have,
Angle of depression = 22°
Altitude = 1800 m
Sin 22° = Opposite/Hypotenuse
=> Sin 22° = Altitude/x
=> Sin 22° = 1800/x
=> x × Sin 22° = 1800
=> x = 1800/Sin 22°
=> x = 1800/0.3746065934
=> x = 4805.04089 m
Answer:
pretty sure it would be 7x-3
