Cd is the perpendicular bisector of both xy and st, and cy=20. find sx.

a. 4
b. 5
c. 6
d. 7

B.5

Step-by-step explanation:

In the figure, the measurement of is 20. The measurement of is 15.

In this triangle we can see that the measurement of and are the same.

We can then assume that will be the different between and

20 - 15 = 5

So = 5.

step-by-step explanation:

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
