Work out size of angle x

angle x = 84°

Step-by-step explanation:

To find angle x, we have to know that the sum of angle in a circle  is 360°  and a right angle is 90°

Which implies, If we are to add the angles i  the figure above, it will give 360°

We will equate the sum of the angles to 360°. That is;

x + 90°+54°+ 132° = 360°

x + 276°  = 360°

Subtract both-side of the equation by 276°

x + 276°-  276°    = 360° -  276°  

x = 84°

Therefore angle x = 84°

i dont know sorry

step-by-step explanation:

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.
