The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Divide both parts of the equation by sin(60)
We get the answer: x = 20/sin(60)
sin(60)*x = 20
Expand brackets in the left part
sin60x = 20
Divide both parts of the equation by sin(60)
x = 20 / (sin(60))
We get the answer: x = 20/sin(60)
