sum of angle of a triangle is 180°
therefore, (2x+15°) + 85° + (8+20°) = 180°
2x+15°+85°+28° = 180°
2x+100°+28°= 180°
2x + 128° = 180°
2x= 180°- 128°
= 52°
x = 52/2= 26° answer....
hope this helps you....

By applying angle sum property of triangle we get,
2x+15+85+8+20=180
2x+128=180
2x=180-128
2x=52
x=52/2
x=26
2x+15+85+8+20=180
2x+128=180
2x=180-128
2x=52
x=52/2
x=26
wrong
right answer is 20degree
your question might be wrong
