What are the lengths of a right triangle in which one acute angle measures 19 degrees and the hypotnuse is 15 units long

4.884 units, 14.183 units

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relationships between sides and hypotenuse:

... Sin = Opposite/Hypotenuse

... Cos = Adjacent/Hypotenuse

Then the Opposite and Adjacent sides can be found by multiplying the sine and cosine of the angle by the length of the hypotenuse.

... short side = 15 · sin(19°) ≈ 4.884 units

... long side = 15 · cos(19°) ≈ 14.183 units

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.  

answer: 193

explanation:

200-7 = 193
