Answer:
y = 3.46
Step-by-step explanation:
In the picture attached there are two triangles smaller and the bigger one.
Both the triangles are right angle triangles.
In both the triangles there is a common side which is hypotenuse of the smaller triangle and the same is base for larger one.
Now from smaller triangle


We cross multiply on both sides
h = 2
Now in the bigger triangle
tan60 = 

y = (√3)(2) = 2√3 = 3.46
Answer is y = 3.46
