Given data ∠ T2 , Cos of ° =

T-2x , adjacent side T-2 , hypotenuse

T-1+ T-2=

Given data ∠ T1 , Cos of ° =

T-1x , adjacent side T-1 , hypotenuse

∑F_y=0 , This symbol means adding all the forces along y-axis, it must be zero for equilibrium.

∑F_y = 0; T-1_y + T-2_y - W = 0

Given data ∠ T2 , Sine of ° =

T-2y , Opposite side T-2 , hypotenuse

∑F_y=0; T-1+ T-2= W , Given Data

Given data ∠ T1 , Sine of ° =

T-1y , Opposite side T-1 , hypotenuse side

ANSWER: T-1 T-2

Sine of angle = opposite side of angle divided by hypotenuse.

Cosine of angle = adjacent side of angle divided by hypotenuse
