Question

Find the length of the indicated side.

10.4 cm
9.5 cm
11.7 cm
8 cm

Answer 1

9.5 cm

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

9.5 cm

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)}`

`=√(10^2-3^2)`

`=√(100-9)`

`=√(91)`

`=9.539392014169...`
