An isosceles triangle has one angle with a measure greater than 95° and another with a measure of x°. Which of the following must be true?
A
x > 85
B
x = 85
C
x =42.5
D
x <42.5
E
x > 42.5
参考答案
参考解析
解析：
等腰三角形有两个角相等，且三角形内角度数总和为180度，所以不可能有两个角大于95度，故其他两个角为x度。假设其中一个角为96度。则x + x + 96 = 180 , 2x = 84, x = 42,根据以上选项，可知D为正确选项。
