let first angle be X
according to questions
X + 2x+ (X+20)=180
3x =160
X = 160/3
largest angle is
second angle = 320/3

Given ; The second angle of a triangle is twice as large as the first. The measure of the third angle is 20
degrees greater than the first
To Find ; Large are angels
Solution ; Let the first angle is x
Then according to question
Second angle of triangle = 2x
Third angle of triangle = x+20
Angel sum of a triangle is 360 that is the sum if all the angles of a triangle together make a sum of 360
In triangle sum of all angles in 360
x+2x+x+20=360
4x=340
x=85
Second angle = 170
Third angle = 105
Hence the three angles are 85, 170 and 105
