To solve this triangle, we need to find the missing side and angles.

Given:
y = 9
z = 6.5

First, we can find the missing angle by dividing 72° by 2:

Now, we can use the Law of Sines to find the missing side x:
sin(x) / x = sin(y) / y
sin(x) / x = sin(36°) / 9
sin(x) = (x * sin(36°)) / 9
sin(x) = (x * 0.5878) / 9
sin(x) = 0.0653x

Now, we can use the Law of Sines to find the missing side x:
sin(x) / x = sin(z) / z
sin(x) / x = sin(6.5) / 6.5
sin(x) = (x * sin(6.5)) / 6.5
sin(x) = (x * 0.1132) / 6.5
sin(x) = 0.0174x

Now, we can set the two expressions for sin(x) equal to each other:
0.0653x = 0.0174x
0.0653x - 0.0174x = 0
0.0479x = 0
x = 0 / 0.0479
x = 0

Therefore, the triangle is not possible to solve with the given information.

Given data:

In triangle △x72,
y = 9
z = 6.5

To find:
x

Using the sine rule, we have:

x/sin x = y/sin y = z/sin z

Since

We don't have the value of
Since the sum of the interior angles of a triangle is 180°, we have:


Substituting the given value of
