ANSWER
EXPLANATION
The equation of the given line is
This line is in the slope -intercept form,
where
is the slope.
The line which is parallel to this line and passes through (1,11) also has slope
Let the equation of this line be
This implies
We substitute x=1 and y=11 to get
The required equation is
Answer:
John ski down the mountain is 1285.37 feet.
Step-by-step explanation:
Given : John is skiing on a mountain with an altitude of 1200 feet. The angle of depression is 21.
To find : About how far does John ski down the mountain ?
Solution :
We draw a rough image of the question for easier understanding.
Refer the attached figure below.
According to question,
Let AB be the height of mountain i.e. AB=1200 feet
The angle of depression is 21 i.e.
We have to find how far does John ski down the mountain i.e. AC = ?
Using trigonometric,
Therefore, John ski down the mountain is 1285.37 feet.
