Please help me solve this question

x=12

Step-by-step explanation:

The shapes are similar, so their corresponding sides will be proportionate

Use the bases and the right most sides to create the proportion

14/56=3/x

Cross multiply

14*x=56*3

14x=168

Divide both sides by 14

x=12

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.  

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
