Cindy is 72 inches long. Imagine it like a right triangle. Her shadow is the base, she is the side, and the distance between her head and the end of the shadow is the diagonal line connecting the two. Use the Pythagorean theorem to find how tall cindy is.
a²+b²=c² a=21, the length of the shadow
b= ? cindy's height
c= 75, the distance from her head to the edge of the shadow
21²+ b²=75²
441 +b² = 5625
-441 -441
------ -------
0 5184
b² = 5184
√b² =√5184
b= 72

Answer:
y=0/-6x-3 or Undefined
Step-by-step explanation:
Since the slope is only a vertical line, that means the slope is going to be undefined. However, this is what the equation would look like.
Hope this helped!
Use the equation of -b/2a, so if you have a line you can just plug in the numbers.
