Special Right Triangles

first option

Step-by-step explanation:

Using the sine/ cosine ratios in the right triangle and the exact values

sin30° = , cos30° =

sin30° = = = ( cross- multiply )

2x = 32 ( divide both sides by 2 )

x = 16

----------------------------------------------------------

cos30° = = = ( cross- multiply )

2y = 32 ( divide both sides by 2 )

y = 16
