Question

Q7. In quadrilateral ABCD , ∠A : ∠ B : ∠C : ∠ D= 3 : 4 : 6 : 7.Find all the angles of the quadrilateral

Answer 1

Step-by-step explanation:

suppose Angle A = 3x

Angle B = 4x

Angle C = 6x

Angle D = 7x

sum of all the angles in a quadrilateral is = 360

3x + 4x + 6x + 7x = 360

20x = 360

x = 360÷20

x = 18°

Angle A = 3x =》3×18 =》54°

Angle B = 4x =》4×18 =》72°

Angle C = 6x =》6×18 =》108°

Angle D = 7x =》7×18 =》126°
