Question

Find the missing the side of the triangle. A. 0 yd B.√30 yd C. 2√5. yd D. √17 yd

Answer 1

x = 2√5 yd

Explanation:

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

Using Pythagoras theorem we have

a² = b² - c²

where a is the hypotenuse

From the question x is the hypotenuse

Substitute the values into the above formula

We have

`{x}^(2) = ( { √(10) })^(2) + (√(10) )^(2)`

`{x}^(2) = 10 + 10`

`{x}^(2) = 20`

Find the square root of both sides

We have the final answer as

x = 2√5 yd
