PLEASE HELP !!
The figure shows three right triangles. Triangles ABD, CAD, and CBA are similar.
Theorem: If two triangles are similar, the corresponding sides are in proportion.
Using the given theorem, which two statements help to prove that if segment BC is x, then x2 = 74?
1) Segment BC ⋅ segment DC = 49
Segment BC ⋅ segment BD = 35
2) Segment BC ⋅ segment DC = 49
Segment BC ⋅ segment BD = 25
3) Segment BC ⋅ segment DC = 25
Segment BC ⋅ segment BD = 35
4) Segment BC ⋅ segment DC = 25
Segment BC ⋅ segment BD = 49
