A mass of 20kg is suspended from a ceiling by two lengths of rope that make angles of 30^o and 45^o with the ceiling. Determine the tension in each of the ropes.

i drew the triangle and found out the other angles using triangle properties and ended up with

T1/sin45=T2/sin60=196N/sin95

T1=196(sin45)/sin95=139.1 N and T2=196N(sin60)/sin95=170.3N

the book shows the answers to be 143.48N and 175.73N and i can't figure out how i went wrong
