By definition, two triangles are similar if all their corresponding angles are congruent and their corresponding sides are proportional. It is not necessary to check all angles and sides in order to tell if two triangles are similar. In fact, if you only know that two pairs of corresponding angles are congruent that is enough information to know that the triangles are similar. This is called the AA Similarity Postulate.
AA Similarity Postulate: If two angles in one triangle are congruent to two angles in another triangle, then the two triangles are similar.

Answer:
Therefore the number of stud in those wall are= 8.5125
Step-by-step explanation:
Given that load bearing walls required a stud every feet feet.
To cover feet long wall needs 1 stud
Then the number of stud in 8 feet long wall are
= 6
Again the number of stud in 6.7 feet long wall are
= 2.5125
Therefore the number of stud in those wall are = (6+2.5125)
=8.5125
Answer:
Step-by-step explanation:
The 2 smaller triangles are proportionate to one another because they are 2 parts of the same larger triangle. Setting up the proportion, one triangle at a time:
and cross multiply to get
6.7x = 96.28 so
x = 14.37 or 14.4, choice A.
