Answer:
fourth option
Step-by-step explanation:
Using the sine and cosine ratios in the right triangle and exact values
sin60° = , cos60° =
, then
sin60° = =
=
( cross- multiply )
2x = 4 ( divide both sides by 2 )
x = 2
---------------------------------------------------------
cos60° = =
=
( cross- multiply )
2y = 4 ( divide both sides by 2 )
y = 2

So hmm check the picture below
using the 30-60-90 rule, we get that much.. .bear in mind, an equilateral triangle has all equal sides, and therefore, all equal angles, so each angle is 60°, run a median through it from the center, and you split it in half
