Ayudaaaaaaaaaaaaaaaaaaaaaaaaa

Answer 1

Explicación paso a paso:

=> Si A y B son agudos y complementarios

25.El ∠A = 34°:

=> ∠B = 90 -  34 = 56°

26. El ∠B = 60°:

=> ∠A = 90 - 60 = 30°

27. SenB = 0,766044:

=> Cos A = 0,766044

28. Cos A = 0,939692:

=> Sen A = 0,939692

29. Tan A = 1:

=> Tan B = 1

30. Cos 60 = 0,5:

=> Sen 30 = 0,5

31. Tan 35 = 0,7:

=> Tan 55 = 0,7

32. Cos 70 = 0,3420201:

=> Sen 20 = 0,766044
