Step-by-step explanation:
Hello There!
This is an example of a 30 - 60 - 90 triangle
We are given the long leg and we need to find the hypotenuse
First we want to find the shorter leg
To do so we just take away the from the 4
so the shorter leg is equal to 4
Now to find the hypotenuse
Well according to the 30-60-90 triangle rule
the hypotenuse is equal to twice the size of the short leg
4*2=8
hence, the answer is option 2
