Answer 1

I'm guessing =55 degrees, 55 minutes.

Convert it into only degrees. 55(1/60)= 55.9166 degrees.

Answer 2

*55+(55*(1/60)) degrees

Answer 3

Instead of 55.91666666, I'll use the fraction (671/12)

Answer 4

B degrees = 180 - (671/12) = (1489/12) degrees, or 124.083333 degrees.

Answer 5

Lets find a

sin(671/12 degrees) = (a/16)

Answer 6

Multiply each side by 16

16*sin(671/12) degrees = a

Answer 7

a = 13.25
