Answer:
The angle that the line makes with x-axis of of 64.3º.
Step-by-step explanation:
Equation of a line, and angle with the x axis:
The equation of a line has the following format:

In which m is the slope.
The angle that the line makes with the x axis is given by the angle which has tangent m, that is,
.
In this question:
We have that
. So

The angle that the line makes with x-axis of of 64.3º.
Answer:
4.58 miles
Step-by-step explanation:
The Pythagorean theorem is used to answer such questions. It tells you the relation between the side lengths is ...
AC² = AB² +BC²
In miles, ...
5² = AB² + 2² . . . . . . . fill in the given numbers
25 -4 = AB² . . . . . . . . subtract 2²
√21 = AB ≈ 4.58 . . . . . take the square root
The distance in miles from A to B is about 4.58.
