Question

Please help me I’m struggling :’(

Answer 1

B.
`x = √(40)`

Explanation:

Using Pythagorean theorem, find the value of x.

Pythagorean theorem is given as
`c^2 = a^2 + b^2`

Where,

c is the longest side of a right angled ∆ = the hypotenuse = x

a and b are legs of the right angled ∆ = 2 and 6

Plug in the values into the equation and solve for x

`x^2 = 2^2 + 6^2`

`x^2 = 4 + 36`

`x^2 = 40`

`x = √(40)`
