Пошаговое объяснение:

1. sin α = 6 / 10 = 0,6

cos α = 8 / 10 = 0, 8

tg α = 6 / 8 = 0,75

ctg α = 8 / 6 = 1 1/3

sin β = 8 / 10 = 0,8

cos β = 6 / 10 = 0, 6

tg β = 8 / 6 = 1 1/3

ctg β = 6 / 8 = 0,75

2. sin α = 5 / 13

cos α = 12 / 13

tg α = 5 / 12

ctg α = 12 / 5

sin β = 12 / 13

cos β = 5 / 13

tg β = 12 / 5

ctg β = 5 / 12

3. sin α = 6 / 10 = 0,6

cos² α = √ 1 - sin ²α = √1 - 0.36 = √ 0.64

cos α = 0.8

tg α = sin α /cos α = 0.6 / 0.8 = 0.75
