What is the measure of angle C? A. 50 degrees B. 60 degrees C. 70 degrees D. 80 degrees 相关知识点: 试题来源: 解析 A。三角形内角和是 180 度,已知角 A 和角 B 的度数,那么角 C 的度数为 180 - 60 - 70 = 50 度,所以选 A。
A. 30 degrees B. 60 degrees C. 90 degrees D. 120 degrees 相关知识点: 试题来源: 解析 B。等边三角形的三个角相等,三角形内角和为 180 度,所以每个角的度数为 180÷3 = 60 度。选项 A 角度过小,选项 C 是直角三角形中直角的角度,选项 D 不符合等边三角形内角和的计算。
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。
百度试题 结果1 题目Do you know what degrees the (angle) of a triangle are? 相关知识点: 试题来源: 解析 1.angles 考查名词复数。分析句子,由 degrees 和 are 可知设空处需要填名词的复数形式,故填 angles。反馈 收藏
A triangle has angles of 60 degrees, 70 degrees, and what other angle? A. 40 degrees B. 50 degrees C. 60 degrees D. 70 degrees 相关知识点: 试题来源: 解析 B。三角形内角和是 180 度。已知两个角分别是 60 度和 70 度,那么第三个角就是 180 减去 60 再减去 70,等于 50 度。
The law of cosines allows us to find parts of a triangle. The law of cosines states that the square of a side is equal to the sum of the square of the other two sides minus the double product of the product of both sides times the cosine of the angle they form. Let a, b, and...
In a triangle, one angle is 60 degrees and another angle is 40 degrees. What is the measure of the third angle? A. 80 degrees B. 70 degrees C. 90 degrees D. 100 degrees 相关知识点: 试题来源: 解析 A。本题考查三角形内角和为 180 度。已知两个角分别为 60 度和 40 度,第三个角则...
In a triangle, if one angle is 60 degrees and the other angle is 40 degrees, what is the measure of the third angle? A. 80 degrees B. 70 degrees C. 90 degrees D. 100 degrees 相关知识点: 试题来源: 解析 A。在一个三角形中,三角形的内角和为 180 度。已知两个角分别为 60 度和 ...
The 180-degree angle is a straight angle and forms a straight line. It is exactly half of the full angle (360-degree angle). Learn about the 180-degree angle, its construction, properties in this article.
