Find the perimeter of a 30°-60°-90° triangle with a hypotenuse of 18. a.p=27 +9/3^- c.p=24+6/3^- b.p= 27+9/6^- d. p=24+3/6^-

note that for a 30°-60°-90° triangle , the sides are 1, √3, 2

If the hypotenuse (2) is equal to 18, find the other lengths

First, find side (1). Divide 18 by 2

18/2 = 9

Next, multiply 9 with √3

9(√3) = 9√3

Finally, find the perimeter. Add all sides:

P = 18 + 9 + 9√3

P = 9√3 + 27

hope this helps

it would be the first answer I think. not very sure
