The answer is 51°.

The top two lines are parallel to each other. Therefore alternate interior angles theorem applies. The bottom right corner that is underneath the line (for lack of a better description) is also 58°.

We also know that a triangle equals 180°. So 58+71= 129°.

So to find that missing angle we subtract 129 from 180 to get the 51°.

Are the two triangles similar?

Tpy6a [65]

Answer:

Option B Yes by AAA

Step-by-step explanation:

we know that

If the two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent

so

$\frac{HM}{MK}=\frac{GM}{MJ}$

substitute the values and verify

$\frac{8}{12}=\frac{6}{9}$

simplify

$\frac{2}{3}=\frac{2}{3}$ -------> is true

therefore

The triangles are similar by AAA------> the three angles are congruent
