We know,sum of all the angles in a triangle is equal to 180
So, 2x + 3x - 11 + 2x + 9 = 180
7x - 2 = 180
7x = 180 + 2
x = 182 / 7
x = 26
Now, magnitude of angles = 2x = 2(26) = 52 [ Smallest ]
3x - 11 = 3(26) - 11 = 78 - 11 = 67 [ Largest ]
2x +9 = 2(26) + 9 = 52 + 9 = 61
In short, Your Answer would be Option A) 52
Hope this helps!
