Answer:
x = 4
y = 8
Step-by-step explanation:
this is a 30-60-90 triangle and the sides have a constant ratio
the side across from the 30°∡ is 1
the side across from the 60°∡ is √3
the side across from the 90°∡ is 2
In this problem we can find 'x' by setting up this proportion:
x/12 = /1
cross-multiply:
x = 12
x = 12/
since we don't like to leave radicals in the denominator, we can multiply both numerator and denominator by to get:
12 ÷
·
(
·
=
, which equals 3)
so we have 12/3, which is 4
The 'y' value will be twice the 30° side, so 8
