Step-by-step explanation:

F ( x ) = x² + 2x - 24

{ factorising by middle term splitting method }

[ 24 = 2 × 2 × 2 × 3 ]

F ( x ) = x² + 6x - 4x - 24

F ( x ) = x ( x + 6 ) -4 ( x + 6 )

F ( x ) = ( x + 6 ) ( x - 4 )

The answer is 30

Explanation:

So all of the angles in a triangle add up to 180 degrees and so if you split the triangle into separate triangles then you can add up the angles that are known and subtract from 180 to get the size of the missing angle e.g 90 + 56 = 146, 180 -146 = 34 for the other triangle 90 + 26 = 116, 180 - 116 = 64 and so 64 - 34 = 30
