$tgCAB= \frac{CB}{CA}$ CB=√(2√13)²-4²=√52-16=√36=6 $tgCAB= \frac{CB}{CA}= \frac{6}{4}= \frac{3}{2}=1,5$

Read the text.
Then choose the correct answer for each question below. Recent scientific studies about hedgehogs have helped to explain mysteries as varied as why hedgehogs apply saliva to their entire bodies, how they have survived on the planet for 30 million years, why they chew toxic toad skins and what secrets they may hold about evolution. As one of the most primitive mammals on the planet, the hedgehog has been helping geneticists understand evolutionary relationships among mammals and even uncover secrets of the human genome. Hedgehogs spend much time alone. But it would be a mistake to consider them solitary. They may occasionally scrap over food items and rival males attracted to a female may also have aggressive interactions. Still, it’s fair to say that, in adulthood, hedgehogs meet primarily to mate, producing litters of four or five hoglets as often as twice yearly.
Choose the correct statement.
a)Evolutionary relationships as well as the secrets of human genome can be studied with the help of different mammals, such as, for example, hedgehogs.
b)The studies of human genome influence on the studies of hedgehogs' evolution. c)The studies of human genome are influenced by the studies of hedgehogs' evolution.
d)There is no correlation between the studies of human genome and hedgehogs' evolution.
