Find the value of x in the isosceles triangle shown below.

C. 10

Explanation:

Take half right triangle from the isosceles triangle:

We get side lengths:

12/2 = 6, 8, and x

And use Pythagorean’s theorem to find x:

6^2 + 8^2 = x^2
36 + 64 = x^2
100 = x^2
10 = x

Lcm of 6 and 8 is 24lcm of 4 and 12 is 12lcm of 11 and 12 is 132 lcm of 3 and 6 is 6

11/2.2 = 5 inches for the length 8.5/2.2= 3.86 inches for the width
