In the figure above, line k is parallel to line m. What is the value of y ?
y =______
选项
答案 17.5
解析 In the figure, the angles with measures(2y)° and 35° are between parallel lines k and m, and they are on opposite sides of the line that crosses k and m.
Therefore, you can conclude that these two angles are congruent. So 2y = 35, and y=35/2=17.5. The correct answer is 17.5.
