Question

Find the value of X rounded to the nearest tenth
A)5.1
B)9.2
C)5.8
D)5.2

Answer 1

B

Explanation:

Chords which intersect have segments whose products are equal. This means the chord with lengths 5 and x has a product 5x. It is equal to the the other chords lengths 5.1 and 9 as a product 5.1*9.

5x = (5.1)(9)

5x = 45.9

x = 9.18

9.18 rounds to the tenth place as 9.2
