Answer 2

Step-by-step explanation:

A +B + C = 180 ( Angle sum property )

3a + 6a + 4a = 180

13a = 180

a= 180/13

Angle A = 3a = 3* 180/13 = 540/3 = 41.5

Angle B = 6a = 6 * 180/13 = 1080/13 = 83.76 = 83.8

Angle C = 4a = 4 * 180/13 = 720/13 = 55.38 = 55.4

A +B + C + D= 360 ( Angle sum property)

41.5 + 83.76 + 55.38 + D = 360

180.64 +D = 360

D = 179.36
