Question

Could someone help, please?

Answer 1

Option B

Explanation:

By using geometric mean theorem in the given right angle triangle RST,

`(RT)/(ST)=(ST)/(VT)`

`(RV+TV)/(ST)=(ST)/(TV)`

`(4.1+10.2)/(ST)=(ST)/(10.2)`

ST² = 10.2 × 14.3

ST =
`√(145.86)`

ST = 12.077

ST ≈ 12.1

Therefore, Option B will be the correct option.
