Use ratios to solve this!
5:6 or 5/6 is the ration for Alex.
<span>Cross multiplication is used to solve this, so:
6x = 5(50) </span>
<span>6x = 250 </span>
<span>x = 250/6 </span>
<span>x = 41.67 which then rounds to 42 feet.
Also to your earlier question here is a screenshot of what the box should look like, and i have circled the attach file icon

Answer:
Option B: 42 feet is the answer.
Step-by-step explanation:
The length of the shadow of the building is = 50 feet
Let the height of the building be = L
Height of Alex = 5 feet
Length of Alex's shadow = 6 feet
Now we will equate the ratios.
L = 41.67 ≈ 42 feet
So, the height of the building is approx 42 feet.
