Question

Could someone help, please?

Answer 1

Answer:

Option B

Step-by-step explanation:

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

$\frac{RT}{ST}=\frac{ST}{VT}$

$\frac{RV+TV}{ST}=\frac{ST}{TV}$

$\frac{4.1+10.2}{ST}=\frac{ST}{10.2}$

ST² = 10.2 × 14.3

ST = $\sqrt{145.86}$

ST = 12.077

ST ≈ 12.1

Therefore, Option B will be the correct option.
