using Pythagorean theorem

c^2=a^2+b^2

c=9in ,a=7in,b=xin

9^2=7^2+x^2

Find the length of BC, in simplest radical form.

zubka84 [21]

9514 1404 393

Answer:

BC = 16 +12√3

Step-by-step explanation:

In the attached, we see that ∆ABE is a 30°-60°-90° triangle with AB the short side and BE the hypotenuse. Then BE = 2·AB = 12√3.

EC is the side opposite AD in parallelogram ADCE, so is the same length, 16.

The length BC is ...

BC = EC +BE

BC = 16 +12√3
