For example, an acute angle measures less than 90 degrees, while an obtuse angle measures more than 90 degrees but less than 180 degrees.Answer and Explanation: The reflex angle of 90 degrees is 270 degrees. A reflex angle measures greater than 180 degrees but less than 360 degrees. When ...
If one angle is 100 degrees, what is the measure of the other angle? A. 80 degrees B. 90 degrees C. 70 degrees D. 60 degrees 相关知识点: 试题来源: 解析 A。两个角的和是 180 度,其中一个角是 100 度,那么另一个角就是 180 - 100 = 80 度。反馈 收藏 ...
An angle is 30 degrees more than its supplementary angle. What is the angle? A. 75 degrees B. 105 degrees C. 135 degrees D. 150 degrees 相关知识点: 试题来源: 解析 B。设这个角为 x 度,其补角为 180 - x 度。由题意得 x = 180 - x + 30,解得 x = 105 度。
What is the reference angle for 200 degrees?Unit Circle:The unit circle can be used to illustrate values of different trigonometric functions and to show that trigonometric identities hold. The unit circle has its center at the origin and a radius of one. Angle measures about the origin are ...
A zero gravity position is achieved by lying on your back and raising your legs and head above the level of your heart. It places your body at an angle of 120 degrees called a zero stress zone which is the most relaxed position for your heart and the nervous system. ...
What is the complementary angle of 35 degrees?Using Subtraction to Find Complementary Angles:In mathematics, complementary angles are angles that sum up to 90°. We can use subtraction to find complementary angles. That is, if we are given the measure of an angle, x, then we can find its...
If one angle is 80 degrees, what is the measure of its adjacent angle? A. 80 degrees B. 100 degrees C. 180 degrees D. 20 degrees 相关知识点: 试题来源: 解析 B。平行四边形的邻角互补,和为 180 度。已知一个角为 80 度,其邻角 = 180 度 - 80 度 = 100 度。反馈 收藏 ...
In a triangle, one angle is 60 degrees and another angle is 40 degrees. What is the measure of the third angle? A. 60 degrees B. 80 degrees C. 100 degrees D. 120 degrees 相关知识点: 试题来源: 解析 B。在一个三角形中,三个角的度数之和为 180 度。已知两个角分别为 60 度和 40 ...
From this common terminal side given that the initial side is placed on the x-axis, we can define a coterminal angle as an angle that has a common terminal side. For example, if the given angle is 45∘, the coterminal angle would be −315∘....
Answer and Explanation: Vertical angles occur when two lines intersect, forming four angles. Assuming the lines do not intersect at an exact right angle, there will be two... Learn more about this topic: Vertical Angles | Definition & Examples ...
