The sum of the interior triangles in a triangle is 180, so if we add all the angle measures together, we should get 180. Therefore, we can make an equation like this,

$110-2x+x+50+5x-40=180$

Simplify this.

$4x+120=180$

$4x=60$

$x=15$

Now we can find each angle measure.

$110-2x$

$110-2(15)$

$110-30$

$80$

$x+50$

$15+50$

$65$

$5x-40$

$5(15)-40$

$75-40$

$35$

So the angle labeled $110-2x$ is the largest angle in the triangle.

Answer: if the blue rectangles are x, then x = 1/2

1/2 + 1/2 = 1

the green shapes each = 1

so you have 1 + 1 + 1 = 3 which is true so

x = 1/2
