Find x.
Round to the nearest tenth.
7cm 7cm 10cm x
x = [? ]cm​​

Answer 1

Answer:

4.9 cm

Step-by-step explanation:

To solve this problem you would use the power of a point formula where two chords intersect in the interior of a circle. We get the equation:

7 * 7 = 10 *x

49 = 10x

x = 4.9 cm

Answer 2

Answer:

x = 4

Step-by-step explanation:

the first line (7cm and 7 cm) are the diameter. You add both numbers to get the diameter which would be 14. Then then next line (10 cm and x) would be the diameter as well. You can create an equation for this (10 + x = 14).

Subtract 14-10 and you get 4. Therefore x = 4
