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? Segment BC × segment DC = 49 Segment BC × segment BD = 35 Segment BC × segment DC = 49 Segment BC × segment BD = 25 Segment BC × segment DC = 25 Segment BC × segment BD = 35 Segment BC × segment DC = 25 Segment BC × segment BD = 49
Little bit of confusion. What's x2. It's no where in fig..:P
i think it just gives that to show what x is
Hint: You can find BC by Pythagoras theorem. Then use property of similar triangles to find the options.
@champs i know that but i dont understand anything else. BC = x = 8.602325267
The x2 thing is really confusing me..:O
i think that was just to help you find BC
How much is 8.6^2?
73.96 but if you use the whole number it equals 74
