Based on the tangent theorem, and also applying the Pythagorean theorem, the length of WX is calculated as: 42.1 units.
The tangent theorem states that a right angle is formed at the point of tangency between the tangent and the radius of the circle.
Thus, WXY is a right triangle. Use Pythagorean theorem to find WX.
WX = √(XY² - WY²)
XY = 25 + 23 = 48
WY = 23
Substitute
WX = √(48² - 23²)
WX = 42.1 units.
