Answer:

Step-by-step explanation:

R is midpoint

|<---------------- QS -------------------->|

Q---------------------R--------------------S

8x - 51 3x - 6

find: QS

QR = RS

8x - 51 = 3x - 6

8x - 3x = 51 - 6

5x = 45

x = 45/5

x = 9

QS = QR + RS

QS = (8x - 51) + (3x - 6)

plugin the value of x=9 into the equation above:

QS = (8(9) - 51) + (3(9) - 6)

QS = 72 - 51 + 27 - 6

QS = 42

Geometry pls help !!! Find the value of AB.<br> AB = [?]

V125BC [204]

Answer:

AB = 16 Units

Step-by-step explanation:

In the given figure, CD is the diameter and AB is the chord of the circle.

Since, diameter of the circle bisects the chord at right angle.

Therefore, AE = 1/2 AB

Or AB = 2AE...(1)

Let the center of the circle be given by O. Join OA.

OA = OD = 10 (Radii of same circle)

Triangle OAE is right triangle.

Now, by Pythagoras theorem:

$OA^2 = AE^2 + OE^2 \\10^2 = AE^2 + 6^2 \\100= AE^2 + 36\\100-36 = AE^2 \\64= AE^2 \\AE = \sqrt{64}\\AE = 8 \\\because AB = 2AE..[From \: equation\: (1)] \\\therefore AB = 2\times 8\\\huge \purple {\boxed {AB = 16 \: Units}}$

Just divide by 4 on both sides to isolate n, that gets you 29.
