Question 26
Triangles and QuadrilateralsDetermine the value of x in the fig. above.
- A.134°
- B.81°
- C.53°
- D.46°
Show the answer and explanation
Answer: A (134°)
Explanation
In the triangle, the third angle (bottom left) is 180° − 81° − 53° = 46°. The angle x is opposite it in a cyclic quadrilateral, so x = 180° − 46° = 134°.
