Step-by-step explanation:
Solution given:
By using Pythagoras law
h²=p²+b²
15²=x²+9²
x²=15²-9²
x=√144=12
x=12 is your answer
Answer: C just took the test
Step-by-step explanation:
The line is vertical, so the slope is infinite
Step-by-step explanation:
Given two points with coordinates
and
, the slope of the line passing through the two points is given by the equation

In this problem, the coordinates of the two points are:

and

which means:

Substituting all these values into the equation of m, we find the slope of the line:

The slope is infinite: this is because the line is vertical.
