Answer 1

Answer:

d

Step-by-step explanation:

Using the Altitude- on- hypotenuse theorem

(leg of big Δ )² = (part of hypotenuse below it ) × (  whole hypotenuse), that is

x² = (30 - 6) × 30 = 24 × 30 = 720 ( take square root of both sides )

x = $\sqrt{720}$ = $\sqrt{144(5)}$ = $\sqrt{144}$ × $\sqrt{5}$ = 12$\sqrt{5}$ → d
