解析 C。本题考查三角形内角和为 180 度的英语表达及计算。已知两个角为 30 degrees(30 度)和 60 degrees(60 度),180 - 30 - 60 = 90 degrees,所以答案是 C。A 选项 70 degrees(70 度)、B 选项 80 degrees(80 度)、D 选项 100 degrees(100 度)均不符合。
A. 90 degrees B. 120 degrees C. 150 degrees D. 180 degrees 相关知识点: 试题来源: 解析 A。三角形内角和是 180 度,已知两个角分别是 30 度和 60 度,那么第三个角是 180 减去 30 再减去 60 等于 90 度。选项 B、C、D 不符合三角形内角和为 180 度的条件,错误。反馈...
