Answer:

 \red { Value \: of \: x } \green {= -2 \: Or \: -2 }

 And \: Value \: of \: tan 45\degree = 1

Step-by-step explanation:

x² + 2x + 4 = 0

=> x² + 2 × x × 2 + 2² = 0

=> ( x + 2 )² = 0

 \boxed { \pink { a^{2} + 2ab + b^{2} = ( a + b )^{2} }}

=> ( x + 2 )( x + 2 ) = 0

=> x + 2 = 0 Or x + 2 = 0

=> x = -2 Or x = -2

 And \: Value \: of \: tan 45\degree = 1

Therefore.,

 \red { Value \: of \: x } \green {= -2 \: Or \: -2 }

 And \: Value \: of \: tan 45\degree = 1
