What are the measures of the angles 2: 4: 9

Sum of all angles in a triangle is 180 degrees. If we mark angles as a, b and c, from given ratio we would have: a + b + c = 180 a = 2x b = 4x c = 9x 2x + 4x + 9x =180 15x = 180 x = 12 a = 2x = 24 b = 4x = 48 c = 9x = 118

2:4:9
so  2 + 4 + 9 = 15
180/15 = 12

12*2 = 24
12*4 = 48
12*9 = 108

measures of the angles 2:4:9 = 24:48:108

Answerthe simplified expression isexplanationthe given expression is,let us deal with the bracket first.the two negatives in the parenthesis will become positive.the expression now becomes,we now expand the parenthesis to get,we group like terms to obtain,this simplifies to,
