Answer:


Step-by-step explanation:
We have the following equation:

We can use the quadratic formula given by:

Where:

And replacing we got:


Positive slope- two variables are positively related; that is when x increases, so does y and when x decreases, y decreases also.
negative slope- two variables are negatively related; that is when x increases, y decreases and when x decreases, y increases.
x-intercept- the x-coordinate of a point where a line, curve, or surface intersects the x-axis.
y-intercept- the y-coordinate of a point when a line, curve, or surface intersects the y-axis.
30 times 40= 120
120 divided by 2= 60.
The answer is 60 feet.
Step-by-step explanation:
All 3 angles add up to be 180 due to sum of angles in a triangle.
Given this fact,
