Answer:
25 feet
Step-by-step explanation:
This is a ratio question.
Say the ratio is object : shadow. Then, the person and their shadow is
5 : 4
If the shadow is 20, then the ratio is
flagpole : 20
How do you go from 4 to 20? You multiply by 5. So, if we multiply the person's height by 5, we'll get the height of the flagpole.
5 * 5 = 25 feet
These triangles are similar because 2 pairs of angles are equal. I'm not very familiar with the acronyms in the list but I guess it must be AA.
Answer: y=-1x+5
Step-by-step explanation:
1. Use slope-intercept formula (y = mx + b) to find the slope which is represented by the variable 'b'.
m = ∆y / ∆x
m = -1 / 1
m = -1
y= -1x + b
2. Use any cooresponding x and y values to substitute into the formula. Ex: (x,y) → (1,4)
y = mx + b
4 = -1(1) + b
4 = -1 + b
5 = b
3. Plug in the values found into the formula.
y = -1x + 5
