Answer:
x = 90°, y = 58°, z = 32°
Step-by-step explanation:
The angles in a square = 90° , then
x = 90° ( adjacent angle )
The sum of the 3 angles in a triangle = 180° , then
x + y + 32° = 180° , that is
90° + y + 32° = 180°
y + 122° = 180° ( subtract 122° from both sides )
y = 58°
y + 90° + z = 180° ( straight angle )
58° + 90° + z = 180°
148° + z = 180° ( subtract 148° from both sides )
z = 32°
