2.) Use algebra to find the value of a in the triangle when x=a, y=2a, z=3a. Notice the measurement of the angle is not necessarily the as the value of a.

no such triangle
your sides are in the ratio of
a : 2a : 3a
= 1:2:3
the sides must be such that the sum of any two must be greater than third side
1+2 = 3, not greater than 3
