What is the measure of angle z in this figure?

The value of z in this figure is 137°
Data;
To find the value of z; we know that y = 43°
y = 43°
reason: Opposite angles are equal
But knowing this, we can find the value of z.
But know that z = x = a
However,
[tex]43 + y + x + z = 360^0[/tex]
Reason: Angles at a point equal 360°
But since x = z = a, and y = 43
[tex]43 + 43 + a + a = 360^0\\86 + 2a = 360^0\\2a = 360 - 86\\2a = 274\\a = \frac{274}{2} \\a = 137[/tex]
The value of both z and x is equal to 137°
The value of z in this figure is 137°
