Question

Find each angle shown in the figure. ​

Answer 1

Answer:

Step-by-step explanation: according to the problem,

2y° + 7/2 y° + 5/2y° + 2y°= 360°  [ since, angle at a point is equal to 360°]

⇒2y° + 6y °+ 2y°=360°

⇒10y=360

⇒y=36

therefore

1. 2y=2 x 36= 72 degree

2.3 1/2 y=  7/2 x 36= 126 degree

3.2 1/2 y= 5/2 x 36= 90 degree

4. 2y= 2 x 36= 72 degree
