Answer: y= 97
Explanation:
The triangle sum theorem states that in any triangle, the sum of the three interior angles equals 180°.
42+55+z=180
Z= 83
Angle Y and Z are a linear pair so they equal 180.
y+z= 180
180-83= 97
Y= 97
Answer:
y=97
big triangle:
42+55=97
180-97=83
z=83
small triangle:
180-83=97
26+97=123
180-123=57
x=57
