Two lines intersect at a point. The angles formed at the intersection are $75^\circ$, $45^\circ$, and $055^\circ$ (which can be read as $55^\circ$). The task is to find the angle denoted by $z$.

1. Problem Description

Two lines intersect at a point. The angles formed at the intersection are $75^\circ$, $45^\circ$, and $055^\circ$ (which can be read as $55^\circ$). The task is to find the angle denoted by $z$.

2. Solution Steps

When two lines intersect, they form four angles. The sum of the angles around the intersection point is $360^\circ$. Also, vertically opposite angles are equal.

Given angles are $75^\circ$, $45^\circ$ and $55^\circ$.

Let's denote the four angles as $a$, $b$, $c$ and $z$.

Let $a = 75^\circ$, $b = 45^\circ$, $c = 55^\circ$.

Since the sum of the angles around a point is $360^\circ$,

$a + b + c + z = 360^\circ$

$75^\circ + 45^\circ + 55^\circ + z = 360^\circ$

$175^\circ + z = 360^\circ$

$z = 360^\circ - 175^\circ$

$z = 185^\circ$

3. Final Answer

The angle $z$ is $185^\circ$.
