What is the length of MN? Triangle LMN with L as a 50 degree angle, N is a 50 degree angle. Side ML shows 4x, and side MN shows x + 3.

jim_thompson5910 · Answer

Use the law of sines formula


$$\frac{\sin(50)}{x+3}=\frac{\sin(50)}{4x}$$


$$\frac{1}{x+3}=\frac{1}{4x}$$


$$4x=x+3$$


$$4x-x=3$$


$$3x=3$$


$$x=\frac{3}{3}$$


$$x=\frac{3}{3}$$


$$x=1$$


So the length of MN is $$x+3=1+3=4$$ units
