Answer:
28
Step-by-step explanation:



which is 28.07 degree

x= 23.99
23.99+4=h=28
To solve this problem you must apply the proccedure shown below:
1- You have that the equation of the line is:

Where
is the slope and
is the y-intercept.
2- Based on the information given in the problem, the lines
and
are parallel, which means that both have the same slope. Therefore, you can calculate the slope of
:


3- Use the coordinates of the point
to calculate the y-intercept:

4. Solve for
:

5. The equation of the line
is:

The answer is: 
Answer:
5/7
Step-by-step explanation:
You find a slope by using the equation y2-y1/x2-x1.
In this case: 15-5/21-7
10/14
5/7
