Question

Tan 45 * cos 45 + tan 30 * tan square 60​

Answer 1

`(1)/(√(2))+(3)/(√(3))` , by the way, the simplified is
`2.439157589`

Explanation:

I included a chart so next time you don't need to worry

• tan( 45 degrees) = 1
• cos( 45 degrees) =
  `(1)/(√(2))`

• tan( 30 degrees) =
  `(1)/(√(3))`

• tan squared (60 degrees) is the same as saying square the answer of tan (60 degrees). So tan( 60 degrees) =
  `√(3)` , so square
