Where:
If we want to find f (-2), we substitute , then:
Since we have a negative root, the result will be given by complex numbers. By definition:
So:
Answer:
Answer:
tanI =
Step-by-step explanation:
We require to calculate GH using Pythagoras' identity in the right triangle.
GH² + GI² = HI²
GH² + 5² = ( )²
GH² + 25 = 95 ( subtract 25 from both sides )
GH² = 70 ( take square root of both sides )
GH =
Then
tanI = =
=
