Sec is 1/cos so sec -120 is 1/cos -120 which is -2
Let the integers be x and x + 2, provided x is even.
x(x + 2) = 360
x² + 2x = 360
x² + 2x - 360 = 0
(x - 18)(x + 20) = 0
x = 18, or x = -20
Thus, the integers are: 18 and 20, or -20 and -18

Answer
Find out the how much did they win in total .
To prove
As given
Peter and angad win some money and share it in the ratio 4:1 .
Peter gets £28 .
Let us assume that x be the scalar multiple of the Peter and angad wins money.
Than
Peters money = 4x
Angad money = x
Than the equation
4x = 28
x = 7
Thus
Angad money = x
= £7
The total money peter and angad wins = Peters wins + angad win
= £28 + £7
= £35
Therefore the total cost of the peter and angad wins be £35.
-x+2x=-11+7
x=-11+7
x=-4
