MEDAL!!! The length of the hypotenuse of a30*-60* -90* triangle is 7. Find the perimeter A.7/2+21/2 sqrt3 B.21+7 sqrt3 C. 7+21 sqrt3 D. 21/2 +7/2 sqrt3

OpenStudy (dtan5457):

use this formula of a 30-60-90 triangle to figure out the lengths, and proceed to add them up

OpenStudy (jessiegonzales):

So add 30 60 and 90

jimthompson5910 (jim_thompson5910):

add the sides, not the angles

OpenStudy (jessiegonzales):

60+30=90

jimthompson5910 (jim_thompson5910):

again, you're not adding the angles

jimthompson5910 (jim_thompson5910):

perimeter = sum of all of the sides
