Question

the length of the small leg of a 30-60-90 triangle is 5 what is the perimeter of the triangle?
A.) 5+15√3
B.) 15 +5√3
C.)5/2 + 15/2 √3
D.) 15/2 + 5/2 √3

Answer 1

a = 5. the sides of a 30-60-90 triangle are \[a, 2a, a \sqrt{3}\]

Answer 2

does this help?

Answer 3

no can you help me understand more

Answer 4

ok so you're finding perimeter, which is the sum of all the side lengths. to find the lengths just plug in the value of a (which is 5) into \[a, 2a, a \sqrt{3}\] and simplify

Answer 5

\[5 + 2(5) + 5\sqrt{3}\]

Answer 6

so is my answer B.)
