By taking the product of the two fractions we will see that the number that goes in the green box is a 6.

<h3>How to add two fractions?</h3>

We only can add two fractions if we have the same denominator in both of them, here we want to transform -2/3 in an equivalent fraction, such that the denominator is 9, so we multiply both the numerator and denominator by 3.

So we need to solve:

\frac{-2}{3}*\frac{3}{3} = \frac{-2*3}{3*3}  = \frac{-6}{9}

From that, we can conclude that the number that goes in the green box is 6.

Triangle ABC is similar to triangle LMN by the AA Similarity Postulate.
chubhunter [2.5K]
Well looking at the information in triangle ABC you know 

Angle B + Angle C = 180 - 144

so Angle B + Angle C = 36

since the triangles are similar let angle M = x   

then Angle C = 2x        and angle B = angle M but the similarity postulate

so form an equation 

2x + x = 36 

solve for x 

Hope it helps
