Answer:

The answer is option A

Explanation:

Since the triangle is a right angled triangle we can use the Pythagoras theorem to find the missing side

Using the Pythagoras theorem

That's


{a}^(2) = {b}^(2) + {c}^(2)

From the question

x is the hypotenuse or the longest side of the triangle

Substituting the values into the above formula we have


{x}^(2) = {9}^(2) + {7}^(2)


{x}^(2) = 81 + 49


{x}^(2) = 130

Find the square root of both sides

We have the final answer as

x = √130 m

Hope this helps you
