What is the value of $x$ in the diagram?
Find height of right angle
sin 30 = 1/2 = height/(2 sqrt3) height = sqrt3
Both legs of the triangle on the right are the same length (it is a 45 - 90 - 45 triangle)
use pythagorean principle to calculate x (which is the hypotenuse)
hyp^2 = x^2 = (sqrt 3)2 + (sqrt3)2 You can take it from here !
it says its wrong
