Answer:
sum of the angles in a quadrilateral = 360
x + ( x - 10 ) + ( x + 30 ) + 2x = 360
x + x + x + 2x -10 +30 = 360
5x + 20 = 360
5x = 360 - 20
5x = 340
x = 340 / 5
x = 68
first angle = x = 68°
second angle = x - 10 = 68 - 10 = 58°
third angle = x + 30 = 68 + 30 = 98°
fourth angle = 2x = 2 × 68 = 136°

Answer:
Step-by-step explanation:
As we all know a quadrilateral is always equals to 360°
so,
(2x)+(3x+10)+(4x+15)+(x-5)=360°
10x +10 +15-5=360°
10x = 360-20
x = 340/10
»»=
so the value of x is 34°
Other Angles
(x-5) = 34-5 = 29°
(4x+15) = 136+15 = 151
(3x+10) = 102 + 10 = 112
2x = 68
