Question

In the given figure if MB = 12, MA = 16, MC = 8 then MD = ?
(A) 20
(B) 24
(C) 12
(D) 30​

Answer 1

I think so the answer will be

(A) 20

Explaination

AB is chord of circle

And DC is also a chord of a circle

So, sum of AB=28

Therefore, DC=x+8

28=x+8

x=28-8 =20

Hence, the answer is 20

Answer 2

Answer:

The Answer is B : 24

Step-by-step explanation:

Given that, Mb=12, MA=16, MC=8

Now,

The chords AB & CD intersect each other internally.

∴MD×MC=MA×MB

MD×8=16×12

MD= 16×12 /8

∴MD=24
