Explicação passo-a-passo:

$\\sen=\frac{co}{h} \\cos=\frac{ca}{h}\\ tg=\frac{co}{ca}\\ \\\\a)\\sen=\frac{12}{20}=\frac{6}{5}\\cos=\frac{16}{20}=\frac{1}{5}\\tg=\frac{12}{16}=\frac{3}{4}\\ \\\\\\b)\\sen=\frac{1}{2}=0,5\\cos=\frac{\sqrt{3} }{2}\\tg=\frac{1}{\sqrt{3}}=\frac{\sqrt{3}}{3}\\\\ c)\\\\\alpha \\ \\sen=\frac{24}{26}=\frac{12}{13}\\\\cos=\frac{10}{26}=\frac{5}{13}\\\\tg=\frac{24}{10}=\frac{12}{5}\\\\\\\beta\\\\sen=\frac{10}{26}=\frac{5}{13}\\\\cos=\frac{24}{26}=\frac{12}{13}\\\\tg=\frac{10}{24}=5/12$
