Answer:

B

Step-by-step explanation:

The formula to determine slope is \frac{y-y}{x-x}.

Knowing this you can fill in the formula with the numbers: \frac{2-4}{-8+9}

2 - 4 is -2, so the numerator is -2.

-8 + 9 = 1, so your denominator is 1.

 

Therefore, your fraction is -\frac{2}{1}, or simply -2.

Answer:

Given the 2 values, height and the base, of these 2 triangles, we can assume that they are similar (meaning they share the same angles) as we have no other information to determine the height of the tree.

Therefore, if these triangles are similar, their corresponding sides are proportional. In other words, PZ/RT = QZ/ST or RT/PZ=ST/QZ

Hence, if we find the ratio of this, we can use it to find the side <em>h</em>

<em>QZ/ST=PZ/RT</em>

<em>48/12=PZ/4</em>

<em>PZ/4=48/12</em>

<em>(PZ/4)3=48/12</em>

<em>PZ(3)/12=48/12</em>

<em>48/3=16</em>

16=PZ.
