Question

Find The Value Of y

(A)2
(B) 6/2
(C)2/2
(D)3

Answer 1

A,because I subtract 3 minus 1 equal 2.

Answer 2

value of y is 2√2

C is the correct option.

Explanation:

We can use Pythagoras theorem to find the value of y.

In triangle ABC, using Pythagoras theorem

BC² = AB² + AC²

(8+1)² = 3² + z²

9² = 9 + z²

z² = 81-9

z² = 72

Now, apply Pythagoras theorem in triangle ADC

AC² = AD² + DC²

z² = y² + 8²

Plugging the value of z

72 = y² +64

y² = 72 -64

y² = 8

y = 2√2

Therefore, value of y is 2√2

C is the correct option.
