How did you approach it?

Answer 10

The picture is hard to read because if you look at the pic this way... the lengths could be the same

Answer 11

Well I've know that there is 360 degrees in a circle, but here they are using smaller numbers?

Answer 12

i am thinking if you subtract the two lengths it would give you the small length from b to d

Answer 13

Lets wait see if someone else will chime in. I don't want to solve this the wrong way. Lol

Answer 14

I got 27???

Answer 15

how did you get 27?

Answer 16

C^2=A^2+B^2
Hence; 784=49+B^2??

Answer 17

Why did you use pythag formula?

Answer 18

You can only use pythag form with a right triangle. If you know two sides you can find the third side
