What must be the length of ZY in order for ZY to be tangent to circle X at point Y?

14 units
15 units
16 units
17 units

Step-by-step explanation:

In the image attached you can notice that line ZY is tangent at point Y.

Remember that the radius is always perpendicular to tangents, by definition, that means .

That means is a right triangle where .

All these facts are deducted form having ZY as a tangent.

We know by given that

, becaus it's the radius.

Using Pythagorean Theorem

Solving for

Therefore, the length of ZY must be 15 units to be tangent to circle X.

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6

answer: 0,6

step-by-step explanation:

this would make it the y intercept.
