Step-by-step explanation:

4√3 + 3 =9.92820323

Answer 2

Answer:

3√3 + 4

Step-by-step explanation:

  Since both of the triangles are similar to each other.

⇒ BC / AC = QR / PR

⇒ 8 / 4√3 = 6 / y

⇒ 2 / √3 = 6 / y

⇒ y = 6√3 / 2

⇒ y = 3√3

  Also, because of similarity:

⇒ BA / BC = PQ / QR

⇒ z / 8 = 3 / 6

⇒ z = ( 8 * 3 ) / 6

⇒ z = ( 4 * 2 * 3 ) / 6

⇒ z = 4

   Hence z + y = 4 + 3√3
