问题

In the figure above, XY= YZ. If angle 7=40°, then angle X=?
______°

选项

答案 70

解析 The correct answer is 70. To solve this problem, recognize that the angles opposite the congruent sides will also be congruent. The total of these angles must be 180-40 = 140, so both angle X and angle Z will equal 70°.
