To show: The graph of the following three equations are concurrent. And hence find the coordinates of the point of intersection.

Answer to Problem 7PSB
The point of intersection is
Explanation of Solution
Given:
The given equation of lines are:
Calculation:
The point of intersection of equation
Therefore the point of intersection
The point of intersection of equation
Therefore the point of intersection
The point of intersection of equation
Therefore the point of intersection
As the above solution proved that the graph of three lines are concurrent, therefore the point of intersection of the three lines is

- Can someone help me with this please?arrow_forwardMariela is in her classroom and looking out of a window at a tree, which is 20 feet away. Mariela’s line of sight to the top of the tree creates a 42° angle of elevation, and her line of sight to the base of the tree creates a 31° angle of depression. What is the height of the tree, rounded to the nearest foot? Be sure to show your work to explain how you got your answer.arrow_forward1arrow_forward
