Question

Find the missing the side of the triangle A. 130−−−√ m B. 179−−−√ m C. 42–√ m D. 211−−−√ m

Answer 1

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
