Question 26
Triangles and QuadrilateralsIn the diagram, ΔXYZ is produced to T. If |XY| = |ZY| and ∠XYT = 40°, find ∠XZT.
- A.110°
- B.130°
- C.120°
- D.140°
Show the answer and explanation
Answer: A (110°)
Explanation
The triangle is isosceles with the 40° angle at Y, so ∠YXZ = ∠YZX = 70°. ∠XZT is on the straight line: 180° − 70° = 110°.
