To get from the post office to the library, Sindy walked due north and then due east. The distance Sindy walked east is 20 meters more than the distance she walked north. If Sindy were able to walk directly from the post office to the library in a straight line, she would have walked 150 meters. Suppose x represents the distance Sindy walked north. Which equation can be used to find x?

x^2 (x 20) ^2=150^2

202=x^2-150^2

x (x 20) = 150

x^2 (x 150) ^2=20^2

Technically, none of the equations.

The equation you're looking for would be:

x² + (x+20) ²=150²
