Question

quadrilateral are equal X degrees, (X + 10 degrees) X + 20 (X + 30 find the angles​

Answer 1

the sum of all angles of a quadrilateral = 360°

so,

x +( x +10° )+( x + 20° )+ (x + 30°) = 360°

4 x + 60° = 360°

4 x = 360° - 60°

4 x = 300°

x = 75°

so, angles of quadrilateral will be,

x = 75°

x+ 10° = 85°

x + 20° = 95°

x + 30° = 105°

Answer 2

Answer:

75, 85, 95, 105

Step-by-step explanation:

x + x + 10 + x + 20 + x + 30 = 360

4x + 60 = 360

4x = 300

x = 75
