The diagram shows a right-angled triangle. 9 cm
23°
hcm
What is the value of h?
Give your answer correct to 1 decimal place.

Step-by-step explanation:

Tangent = opposite/adjacent

opposite = 9cm

adjacent = hcm

tan 23° = 9/h

cross multiply

tan 23°×h = 9

h = 9/1•5881

h = 5•7

45

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.
