Question #9f067

Answer 1

`30^@` and `150^@`

Explanation:

Let the second angle equal A

The first angle, therefore, must equal `60^@+3A`

Since the sum of the angles must be `180^@`

`180=A+60+3A`
`120=4A`
`A=30^@`

Substituting the value for the second angle into the formula for the first

`60+3*30`
`=60+90`
`=150^@`

`therefore` the angles are `30^@` and `150^@`
