Find the missing side lengths. Leave your answer as radicals in simplest form.

x = 4, y = 2

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin30° = , then

sin30° = = = ( cross- multiply )

x = 4

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

Using the tangent ratio in the right triangle and the exact value

tan30° = , then

tan30° = = = ( cross- multiply )

y = 2

all it means is function 3

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
