What is the value of y? enter your answer, as an exact value, in the box.

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
