17 x 10 - 4
170 - 4
166
Step-by-step explanation:
The given measurements are:
16 m, 21 m, 39 m
We know that, it is only possible to form a triangle if sum of the measures of any two lengths is always grater than the measure of third length.

Therefore, it is not possible to form a triangle with given measurements.
R = 34x - (4x + 180)
