Question

The length of each segment is as follows: segment OX is 5 units, segment OY is 7 units, segment XY is 3 units, and segment X'Y' is 12.6 units. What is the length of segment OX? 5 X 7 3 12.6. what is the length of segment OX'?

Answer 1

let y be the length of X'O. We get

$\frac{12.6}{3}=\frac{y}{5}\rightarrow y=5\cdot\frac{12.6}{3}=21$
