Find the value of y (a)2 (b) 6/2 (c)2/2 (d)3

value of y is 2√2

C is the correct option.

Step-by-step 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.

b) 36

step-by-step explanation:

18 times 2 is 36
