Answer:
B) x = 8 ; y = 4
Step-by-step explanation:
in a 30-60-90° triangle the sides, respectively, are in the ratio of
1 : : 2
we can find 'x' by creating this proportion:
12/ = x/2
cross-multiply to get:
x = 24
x = 24/
we can simplify this by 'rationalizing the denominator' which is to
multiply numerator and denominator by to get:
(24)÷3, which is 8
we know that side 'y' is half that of side 'x'
therefore y = 4
