I hope this helps, if any doubt leave a comment
Six hundred fifty eight and one hundred twenty nine thousandths
B = 18 because 18-5 is equal to 3 and 3x3 is equal to 9.
8x + 3× + 9x = 180
20x = 180
x = 180/20
x = 9
The smallest angle is: 3×9 = 27 degrees
Note: 180 degrees is the sum of angles in a triangle
I'm sorry I can't see it clearly.
