Question

Find the perimeter and area of a 30-60-90 right triangle with a hypotenuse of 8 m

Answer 1

so the perimeter = 5 + 5√3 + 10 = 15 + 5√3 or appr. 23.66

Explanation:

The sides of a 30-60-90 triangle are in the ratio of

1 : √3 : 2

so your triangle will be in the ratio a : b : 10

a/1 = 10/2

a = 5

b/√3 = 10/2

b = 5√
