A) Yes, because both triangles are right angle triangles, with  similar bases.
Therefore, Similarity Postulate is SAS.

b)  When DE=32 ft, We have to find the width of the river (AB).
To find AB, we use the ratio of similar sides.


22AB=3200
AB=145.45 ft
Which the width of the river.

Width of River is 145.45 ft
