Question

Can anyone please help me answer the question in the picture?

Answer 1

Apply Pythagoras rule .

`"perpendicular"^2+"base"^2="hypotenuse"^2`

Explanation:

• `"perpendicular"^2+"base"^2="hypotenuse"^2`

Here,

• `"perpendicular"=b`
• `"base"=?(x)`
• `"hypotenuse"=2b`

Hence,

`b^2+x^2=(2b)^2`

`=>b^2+x^2=4b^2`

`=>x^2=3b^2`

`=>x=sqrt3 cdot b`

The length of base is `color(red)(sqrt3 cdot b` unit.

Hope it helps...

Thank you...
