Answer: Option D

Explanation:

Hey there!

Here; Looking at it we can state that it is a Right angled triangle.

And must use the Pythagoras relation if the triangle is a Right angled triangle.

So, let's work on it.

Let ABC be a triangle.

Taking reference angle as C, we get;

perpendicular= 3m

Hypotenuse= 7m

Base = xm

Now;

${h}^(2) = {p}^(2) + {b}^(2)$

$or \: b = \sqrt{ {h}^(2) - {p}^(2) }$

Put all values.

$b = \sqrt{ {7}^(2) - {3}^(2) }$

Simplify to get answer.

b = √(49 - 9)

b = √(40)

Therefore, X= 6.3m.

Hope it helps...
