Step-by-step explanation:
Using the sine and cosine ratios in the right triangle
sin30° = =
Multiply both sides by y
y × sin30° = 6 ( divide both sides by sin30° )
y = =
= 12
---------------------------------------------------------------------------------------
cos30° = =
Multiply both sides by y ( y = 12 )
12 × cos30° = x
x = 12 × = 6
