Question

If a, 2a, 4a and 5a are the angles of
quadrilateral, find them​

Answer 1

a=30,2a=60,4a=120,5a=150 total360

Answer 2

Answer:

30° , 60°, 120°, 150°

Step-by-step explanation:

Ang. 1 = a

Ang.2 = 2a

Ang.3 = 4a

Ang. 4 = 5a

Sum of all angles of quadrilateral = 360°

a+ 2a + 4a +5a = 360°

12 a = 360°

a = 360°/ 12 = 30°

so,

Ang. 1 = a = 30°

Ang.2 = 2a=2×30° = 60°

Ang.3 = 4a= 4×30°=120°

Ang. 4 = 5a=5×30° = 150°
