Answer:
X=50°
Step-by-step explanation:
Let, the fourth angle in the quadrilateral be ∠A
The sum of all the four angles of the quadrilateral is 360°
So 40° + 110°+80°+∠A=360°
230°+∠A=360°
∠A=360°-230°
∠A=130°
The fourth angle of the quadrilateral is 130°
The angle A and X are the angles on a straight line
The sum of the angles on a straight line is 180°
so, ∠A+∠X=180°
130°+∠X=180°
∠X=180°-130°
X=50°
Let thw second integer be x
then the first = 2x
and the third integer is = 6+x
their sum = 74
x+2x+6+x = 74
4x +6 = 74
4x = 74-6 =68
x =68÷4
x = 17
then the first integer is 2×17 = 34
the third integer is 17+6 = 23
the integers are 17 , 23 and 34
