What is the length of the short leg in the 30-60-90 triangle shown below?

Answer:
Correct option is:
B. 5
Step-by-step explanation:
The triangle is a right angled triangle.
Let a be a angle adjacent to 90°
then, tana=Side opposite to angle a/Side adjacent to angle a which is not the hypotenuse
Here, Let a=60°
[tex]tan60\°=\dfrac{5\sqrt{3}}{Length\ of\ short\ leg}[/tex]
[tex]\sqrt{3}=\dfrac{5\sqrt{3}}{Length\ of\ short\ leg}[/tex]
⇒ Length of short leg=5
Hence, Correct option is:
B. 5
