Answer 1

$1)\\\\sin\alpha = \frac{BC}{AB} \\cos\alpha = \frac{AC}{AB} \\tg\alpha =\frac{BC}{AC} \\\\2)\\\\sin\alpha = \frac{IK}{IL} = \frac{10}{26} = \frac{5}{13} \\cos\alpha = \frac{KL}{IL} = \frac{24}{26} = \frac{12}{13}\\tg\alpha = \frac{IK}{KL} = \frac{10}{24} = \frac{5}{12}$

Answer 2

Ответ:

sina=5/13

cosa=12/13

tga=5/12

Пошаговое объяснение:

$sin\alpha =\frac{CB}{AB} \\cos\alpha =\frac{AC}{AB} \\tg\alpha =\frac{CB}{AC}$

sina=10/26=5/13

cosa=24/26=12/13

tga=10/24=5/12
