HI Chris M Please let me know what information you need i did not get all the answers just 4 thanksCustomer

HelloCustomer

Sorry, I accidentally hit "answer" before I was finished. I have them all except #16 and #17. The images and measurements of the sides don't give an answer that matches any of the choices. In a right triangle, a^2 + b^2 = c^2. Could you check these two to make sure they are posted correctly?

Thanks
