Question

Find the value of x. 7 D 3 B В х С X =

Answer 1

Answer:

x = $\sqrt{30}$

Step-by-step explanation:

Using the Altitude- on- Hypotenuse theorem

(leg of Δ ABC )² = (part of hypotenuse below it ) × ( whole hypotenuse )

x² = 3 × (3 + 7) = 3 × 10 = 30 ( take the square root of both sides )

x = $\sqrt{30}$
