Going by the indices provided, if the measure of Angle BZD is (3x) then, x = 17°. The proof is angle on a straight line.

What is Angle on a straight line?

The total angle on a straight line is given as 180°.

Since ∠AZC = 90°; and

∠CZB = 39°; hence,

∠BZD = 180 - (90 + 39) = 51.

If  ∠BZD = 3x

Then 3x = 51

x = 51/3

x= 17°
