Answer:
42°
Step-by-step explanation:
the exterior angle is equal to the sum of the 2 far angles from it (from the exterior angle)
so 98-56=42°
hope you understand it
42
line TZY is a straight line
Total angles on a straight line is 180
Since angle XZT + XZY = 180
98 + XZY = 180
XZY = 82
angle XYZ + YXZ + XZY = 180
XYZ + 56 + 82 = 180
XYZ + 138 = 180
XYZ = 180 - 138
XYZ = 42

b2+5)(−b2+7)
=(b2)(−b2)+(b2)(7)+(5)(−b2)+(5)(7)
=−b4+7b2−5b2+35
