Question 107073
Let angle b=x

so angle a =3x (3 times larger than b)

because of the angle sum of a triangle, c = 180-x-3x
                                          =180-4x

  angle a is 16 degrees larger than c so angle c+16 =angle a

3x(angle a)=180-4x(angle c) + 16
3x=196-4x
7x=196
x=28

x was equal to b so b=28 degrees
a=3 times 28 = 84
c is a-16= 84-16=68
