Answer:
63°
Step-by-step explanation:
Angle <2 and the angle with measure of 63 are alternate exterior angles and has same measurement.
Writing the slope-intercept form of a linear equation, we have:

Where m is the slope and b is the y-intercept.
Since parallel lines have the same slope, we can see that the slope of the line y = 2/3x + 1 is equal m = 2/3, so for our equation we also have m = 2/3.
Now, using the point (0, -4), we have:

So our equation is:

y = 2/3x - 4
To write it in simplest form, you must find a common factor.
In

, 3 is a factor of both 3 and 9
3÷3=1 and 9÷3=3
So


is your answer in simplest form.
5 miles high is one of the sides of a triangle depending on accuracy level
h^2=x^2+y^2
we don't have 2 distances
Tan A=O/a
O=a tan A
We solve for O because the angle is at the top of the line going up and we want the opposite angle that is along the ground
O=5×tan(173.7/2)=90.854033512
The distance he can see is:
90.85*2~181.7 miles
Now we need to find the distance between lines:
The north south distance between each line is 69 miles
thus the number of degrees he will see will be:
181.7/69
=2 19/30
