Question

Find x
5x − 11
38.4
16
10

Answer 1

x = 7

Explanation:

given 2 intersecting chords inside a circle then the product of the parts of one chord is equal to the product of the parts of the other chord , that is

16(5x - 11) = 38.4 × 10 = 384 ( divide both sides by 16 )

5x - 11 = 24 ( add 11 to both sides )

5x = 35 ( divide both sides by 5 )

x = 7
