Question

Find the value of x to the nearest tenth.

Answer 1

x = 8.9 (nearest tenth)

Explanation:

6^2 - 4^2 = 36 - 16 = 20

So

x = 2 * (√20)

x = 2 * 4.47

x = 8.94

Answer 2

The value of x = 4√5

Explanation:

Points to remember

For a right angled triangle

Hypotenuse² = Base² + Height²

To find the value of x

From the figure we can see a right angled triangle with,

hypotenuse = 6 and height = 4

Value of x = 2 * base

we have, Hypotenuse² = + Height²

Base² = Hypotenuse² - Height²

= 6² - 4²

= 36 - 16 = 20

Base = √20 = 2√5

x = 2 * 2√5 = 4√5

The value of x = 4√5
