First, we solve both equations for y, that is:
&
From this we can see that they are parallel lines, that do not share any common points, so there is no solution for the system.
Answer:
Option C is correct
Step-by-step explanation:
Given: A plane is descending onto the runway with an angle of depression of 55°. Also, it has 2.8 miles to go before landing.
To find: current altitude of the plane
Solution:
Consider the attached image.
In ΔABC,
(Alternate interior angles)
For any angle ,
= side opposite to angle/side adjacent to angle
Put
So, the current altitude of the plane is 4 miles.
