The given Angles (4x + 2) and (3x + 3) are forming linear pair, so

$4x + 2 + 3x + 3 = 180$

$7x + 5 = 180$

$7x = 180 - 5$

$7x = 175$

$x = \dfrac{175}{7}$

$x = 25$

now, let's find Angle DCB :

$3x + 3$

$(3 \times 25) + 3$

$75 + 3$

$78 \degree$

The difference between two positive integers is 3. If the smaller is added to the square of the larger, the sum is 87.

Komok [63]

Let x be larger integer so x-3 is the smaller
so x^2+ x-3 = 87
x^2 +x -90=0 and factor
(x-9)(x+10)=0
x=9 or x=-10 but x must be positive
so x=9 and smaller number is 6
