Answer:
140° and 40°
Step-by-step explanation:
let x be one angle then the other is x - 30
Since the angles are a linear pair, theis sum is 180° , then
x + x - 30 = 180, that is
x - 30 = 180 ( add 30 to both sides )
x = 210 ( multiply both sides by 2 to clear the fraction )
3x = 420 ( divide both sides by 3 )
x = 140
and x - 30 =
(140) - 30 = 70 - 30 = 40
The 2 angles are 140° and 40°
