Law of Sine with unknown variable

draw a straight line from the angle at the top (42), it will give two right angled triangles-the one on the left will have 22 degrees at the top while the one on the left will give you the 20 degrees at the top.proceed from there good luck

I'm still lost can you please go on ?

Don't know how to work this input stuff, but here we go.

It's just a normal equation, and you should aim on solving just like any equation.

x/sin(42) = (x+5)/sin(70)

x * sin(70)/sin(42) = x + 5

x * sin(70)/sin(42) - x = 5

x * (sin(70)/sin(42) - 1) = 5

x = 5 / (sin(70)/sin(42) - 1)

Hope it helped.
