Which expression can be used to determine the length of segment zy? see image.

Step-by-step explanation:

ZY is the hypotenuse of triangle XZY.

The two shorter legs are;

YX=3 units

and

XZ=8 units.

According to the Pythagoras Theorem;

This implies that;

We take the positive square root to obtain;

The second choice is correct

step-by-step explanation:

try remembering the steps

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
