Answer» We know,Sum of all angles of triangle is 180° Then,(5y - 15) + (6y - 15) + 9y = 180 20y - 30 = 180 20y = 210 y = 210/20 = 10.5 Therefore, value of y = 10.5Angles are:(5y - 15) = 510.5 - 15 = 37.5°(6y - 15) = 610.5 - 15 = 48°9y = 9*10.5 = 94.5°

Answer»

We know,Sum of all angles of triangle is 180°

Then,(5y - 15) + (6y - 15) + 9y = 180

20y - 30 = 180

20y = 210

y = 210/20 = 10.5

Therefore, value of y = 10.5Angles are:(5y - 15) = 5*10.5 - 15 = 37.5°(6y - 15) = 6*10.5 - 15 = 48°9y = 9*10.5 = 94.5°
