Question

Find the value of sides RS

Answer 1

RS = 15 units

Explanation:

Given:
RT = 9
TS = 12

To find: Length of RS

Proof:

In right triangle RTS,


`RT^(2) + TS^(2) = RS^(2)`

`9^(2) + 12^(2) = RS^(2)`

`81 + 144 = RS^(2)`

`225 = RS^(2)`

`√(225) = RS`
15 = RS
∴ The length of RS is 15 units.
