Answer 2

To solve this problem you must apply the proccedure shown below:

1. You know that the sum of the angles is
`360` degrees. Therefore, you must sum them and solve for
`a`:

`a+a+2a+2a=360`

`a=60` degrees

2. Therefore, the angles are:

`a=60` degrees

`2a=2(60)=120` degrees

The answers are:

`a=60` degrees

`60` degrees,
`60` degrees,
`120` degrees,
`120` degrees
