Ответ:
7 sqrt(2)= BC
7 sqrt(2)= AB
Step-by-step explanation:
sin 45 = opp / hyp
sin 45 = BC / 14
Multiply each side by 14
14 sin 45 = BC
Sin 45 = sqrt(2)/2
14 sqrt(2)/ 2 = BC
7 sqrt(2)= BC
cos 45 = adj / hyp
cos 45 = AB / 14
Multiply each side by 14
14 cos 45 = AB
cos 45 = sqrt(2)/2
14 sqrt(2)/ 2 = AB
7 sqrt(2)= AB
