Question

Find the length of the indicated side. 10.4 cm 9.5 cm 11.7 cm 8 cm

Answer 1

Answer:

9.5 cm

Step-by-step explanation:

on the bottom with 18, divide that like 3 12 3 (which is 18) and it will make a square in the middle.

10^2 = x^2+3^2

100= x^2+9

x^2=91

square root 91

=9.5 cm

Answer 2

Answer:

9.5 cm

Step-by-step explanation:

18 - 12 = 6

6/2 = 3

If we apply the Pythagorean theorem in the right triangle ABC :

AB = ?

AC = 3

BC = 10

We get :

$AB=\sqrt{BC^{2}-AC^{2}}$

      $=\sqrt{10^2-3^2}$

      $=\sqrt{100-9}$

      $=\sqrt{91}$

      $=9.539392014169...$
