Question

Refer to the figure to complete the proportion.

B/X = ?/B

Answer 1

The complete proportion is b/x = c/b

From the figure given, the related ratio is the length of the hypotenus and the opposite side .

For the smaller triangle ;

• hypotenus/ opposite = b/x

For the larger triangle ;

• hypotenus/ opposite = c/b

This is because, the hypotenus of the larger triangle is :

• x + y = c

Therefore, the complete proportion is :

• b/x = c/b
