Answer 1

Answer:

x = 1 (a)

Step-by-step explanation:

1 + 25/144 = 169/144

root 169/144 = 13/12

1 + x/12 = 13/12

x = 1

Answer 2

To find:-

The value of x in $\sqrt{1 + \frac{25}{144}}$ = 1 + $\frac{x}{12}$ .

Solution:-

Here, $\sqrt{1 + \frac{25}{144}}$ = 1 + $\frac{x}{12}$

We know that square root of 1 is always 1.

     ⇒ 1 + $\frac{5}{12}$ = 1 + $\frac{x}{12}$

The Square root of 25 is 5 and square root of 144 is 12.

So, By comparing both side we get,

$x$ = 5, because 1 is common $\frac{x}{12}$ is common.

∴ Option (c) is correct, $x$ = 5.
