Question

Find x. Round to the nearest tenth.

Answer 1

Answer: x = 4.9

Step-by-step explanation: 10*x = 7*7 , which is the same as 10x = 49, divide both sides by 10 to isolate the variable, and you get x = 4.9

Answer 2

x = 4.9

Explanation:

We can use the intersecting chords formula:

(segment piece) x (segment piece) = (segment piece) x (segment piece)

7*7 = 10x

49 = 10x

Divide each side by 10

49/10=10x/10

4.9 = x
