OpenStudy (jessiegonzales):

OpenStudy (studygurl14):

nope. C

OpenStudy (jessiegonzales):

mind explaining

OpenStudy (studygurl14):

You are finding perimeter right? Well the hypotenuse is 18. One side is 18/2, which is 9. And 18 + 9 =27 Then the last side equals sqrt(3) when the hypotenuse equals 2, so when the hypotenuse equals 18, it equals 9sqrt(3)
