Answer:
The triangles are similar, because the angles are congruent and the sides are proportional.
Explanation:
The first step to see if the triangles are similar is to see if the angles are the same.
The third angle in the large triangle is
30 + 65+ unknown = 180
95 + unknown = 180
Subtract 95 from each side
unknown = 180-95
unknown = 85
So the angles are the same.
Lets check the ratio of the the sides
14 10
------ = ----------
7 5
Both simplify to 2/1 so the ratio's are the same.
The triangles are similar because the angles are congruent and the sides are proportional.
