Question

Find the missing side please !!

Answer 1

In the given right triangle base and hypotenuse are given, we have to calculate the length of perpendicular.

Applying Pythagoras theorem in the given triangle which states,

`(Hypotenuse)^(2)=(Base)^(2)+(Perpendicular)^(2)`

`(21)^(2)=(15)^(2)+(x)^(2)`

`441=225+x^(2)`

`x^(2)=441-225`

`x^(2)=216`

`x=6√(6)`
