Explain why the triangles are similar Then find the missing

Explain why the triangles are similar Then find the missing length, x. Choose the reason that the triangles are similar. Both triangles are right and scalene. One angle pair is given to have the same measure (right triangles). Another angle pair consists of vertical angles with the same measure Thus, two angles of the large triangle are equal in measure to two angles of the small triangle All right triangles are similar The Pythagorean theorem states that a^2 +b^2 =c^2. Thus, the corresponding sides are proportional. Find the missing length.

Solution

Answer is b as it is explain in the answer that both are triangles with equal angles.
