Question

Find the value of b if sin 35 degrees equals cos (b + 30) degrees.

Answer this with step by step solutions please.

Answer 1

sin35=cos(b+30)

cos(90-35)=cos(b+30)

55=b+30

b=55-30

b=25

Answer 2

Answer:

$\ \sin(90 - 55) = \cos(b + 30) \\ \\ \cos(55) = \cos(b + 30) \\ \\ 55 = b + 30 \\ \\ b = 55 - 30 \\ \\ b = 25$
