3. Is XY Tangent to circle Z?<br> Y<br> 12 X<br> (20<br> Z<br> 18
Ratling [72]

Answer:

XY is a tangent

Step-by-step explanation:

Given

XY = 12

WY = 20

WZ = 8

Required

Is XY a tangent?

XY is a tangent if:

WY^2 = XY^2 + WX^2

Because XY should make a right angle at point X with the circle

Where

WX = 2 * WZ

So, we have:

WY^2 = XY^2 + WX^2

WY^2 = XY^2 + (2*WZ)^2

WY^2 = XY^2 + (2WZ)^2

WY^2 = XY^2 + 4WZ^2

This gives:

20^2 = 12^2 + 4*8^2

400 = 144 + 256

400 = 400

<em>Yes, XY is a tangent</em>

Answer:

D. The checking account is overdrawn by $15.

Step-by-step explanation:

Since the balance on a checking account represents the remaining money left in that checking account, having a negative value for that would mean an overdrawing of money, or drawing more money than is in that account in the first place.

Therefore, the answer would be that the checking account is overdrawn by $15.

Hope this helped!

In the diagram, line x|| line y. Find the angle measures below.
Yanka [14]

Answer:

<1 = 95

<2 =85

Step-by-step explanation:

<1 = 95

They are alternate exterior angles and alternate exterior angles are equal when the lines are parallel

<1 + <2 = 180  since they form a straight line

95+ <2 =190

Subtract 95 from each side

95-95+<2 =180-95

<2 =85
