sketch a right-angled triangle with angles
30-60-90
label the sides 1 , √3 and 2, with 1 opposite the 30°, etc
so 2 --- x 3.5 -----> 7
and 1 -- x 3.5 -----> 3.5 or 7/2
and √3 -----------> 7√3/2
perimeter = 7 + 7/2 + 7√3/2
= 21/2 + (7/2)√3
1. The length of the hypotenuse of a 30-60-90 triangle is 7. Find the perimeter.
A) 7/2+21/2 sqrt 3
B) 21+7 sqrt 3
C) 7+21 sqrt 3
D) 21/2 + 7/2 sqrt 3
Could someone please help me, I don't know how to do this. Thank you!

I strongly suggest that you memorize the
1 , √3, 2 <------> 30-60-90° triangle.
You will meet it again and again if you continue to study math

I'm gonna do more research on the 30-60-90 triangle. Thank you so much though for helping me!
yes its d
