Answer:
x=76, z=104, y=63
Step-by-step explanation:
The angles in a triangle always add up to 180°. Therefore:
46+58+x=180
∴x=76
The angles in a straight line always add up to 180°. X and Z are along the same line, therefore:
76+z=180
∴z=104
Since the angles in a triangle add up to 180, we can write:
104+13+y=180
∴y=63
