option 4
Step-by-step explanation:
using the sine/ cosine ratios in the right triangle and the exact values
cos30° = , sin30° =
, then
cos30° = =
=
( cross- multiply )
2x = 20 ×
= 20 × 3 = 60 ( divide both sides by 2 )
x = 30
and
sin30° = =
=
( cross- multiply )
2y = 20 ( divide both sides by 2 )
y = 10
