What are the lengths of the missing sides of a 30 60 90 triangle if the longer leg is 18 cm?

1 answer:

7 0

Lengths of a 30 60 90 triangle if longer leg = 18
hypotenuse = 18 * (2/ sq root (3)
short leg = 18 / sq root (3)

hypotenuse = 20.7846096908 
short leg = 10.3923048454

g(x)=\cfrac{-x}{x-3}
\end{cases}\qquad f(x)+g(x)\implies \cfrac{x}{x-9}+\cfrac{-x}{x-3}$

Answer: B) 16 units

Step-by-Step Explanation:

As we can observe from the graph,

Length (l) = 5 units
Breadth (b) = 3 units

Perimeter = 2(l + b)

Therefore,
= 2(l + b)
= 2(5 + 3)
= 2(8)
= 2 * 8
=> 16

Perimeter = 16 units
