Hi there, so we know that all triangles add up to 180 degrees so we will take 38 and add it with 25 to get 63 then we subtract 180 by 63 to get 117 which is your awnser!!

Step-by-step explanation:

Remember that similarity is about having proportional sides and congruent angles. When we have congruent sides, then those rectangles are congruent not similar.

In this case, to find the similarity, Leah should compare bases and heights thorugh division, because the ratio between heights and the ratio between bases must be equal. So, let's divide.

$\frac{21}{6}=3.5$
