We have A
The angles in red have the same measure
The angles in blue have the same measure that is 67°
The sum of and angle red plus an angle in blue is 180°
Therefore in order to find y
y+67=180
Then we isolate the y
y=180-67
y=113°
Then for z we have the next equation
6z-37=113
We isolate the z
6z=113+37
6z=150
z=150/6
z=25
ANSWER
y=113
z=25
