ok thx.. mean i can use (a-b)^2=a^2-2ab+b^2?

Homework Statement Find X? 1.732cos(x)-1.16=sin(x) Answer: X = 24.6 Homework Equations The Attempt at a Solution sin(x) = sqrt(1-cos(x)^2) 1.732cos(x)-1.16=sqrt(1-cos(x)^2) 1.732^2 cos(x)^2 -1.16^2= 1-cos(x)^2 3cos(x)^2-2.3456=1-cos(x)^2 4cos(x)^2=3.3456...

i did try this.. Fx = 0 Fxa=Fxb+fxc Fy=o Fya=Fxb+fxc but i cannot get the right answer...

here.. thx

can anyone pls answer the question on the pic... thx...
