The length of the hypotenuse of a 30degree -60degree -90degree triangle is 18. What is the perimeter?

OpenStudy (studygurl14):
OpenStudy (jessiegonzales):

A. 9+27 sqrt3 B. 18+81 sqrt3 C. 27+9 sqrt3 D.81+9 sqrt3

OpenStudy (jessiegonzales):

I was thinking A?

OpenStudy (studygurl14):

|dw:1412806580326:dw| Does that help?

OpenStudy (jessiegonzales):

so A?

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)
