Chapter 4/ Lesson 14 109K Explore the definition of complementary angles and their types: adjacent and non-adjacent. Also, learn how to find the complement of an angle with examples and applications. Related to this Question What is the complement of 70 degrees?
An angle is 30 degrees more than its complementary angle. What is the measure of the angle? A. 60 degrees B. 30 degrees C. 45 degrees D. 75 degrees 相关知识点: 试题来源: 解析 D。设这个角为 x 度,它的补角为(90 - x)度。已知这个角比它的补角大 30 度,则 x = (90 - x) + ...
There are various ways of solving these types of problems, and one of them is substitution, wherein we substitute one condition (equation) into another, in order to acquire the value of an unknown parameter.Answer and Explanation: We solve for the measure of an...
Right angles are all angles that are exactly 90 degrees and the most obvious in geometry is the triangle. Learn the definition of a right angle and explore the and notation and formula for right angles using the Pythagorean theorem, which relates all sides of a triangle to one another. ...
If an angle is twice as large as its complementary angle, what is the measure of the angle? A. 30 degrees B. 60 degrees C. 45 degrees D. 75 degrees 相关知识点: 试题来源: 解析 B。设这个角为 x 度,它的补角就是 90 - x 度。因为这个角是它补角的两倍,所以 x = 2(90 - x),...
What is a standard angle? What is the degree measure of half of a right angle? To the nearest degree, what is m angle B? In the figure below, r||s, m angle 3 = (5x+16) degrees, and m angle 6 =(10x +14) degrees. What is a measure of angle 1?
The measure of an angle is twice the measure of its complementary angle. What is the measure of the angle? A. 30 degrees B. 60 degrees C. 90 degrees D. 120 degrees 相关知识点: 试题来源: 解析 B。设这个角为 x 度,它的补角就是 90 - x 度。已知这个角是其补角的两倍,可列方程 x...
Two angles are complementary if the sum of the angles is equal to 90º (ninety degrees). For example, an angle that is 30º and an angle that is 60º are two complementary angles.Since 90º is the measurement for a right angle, another way to tell if two angles are ...
the two angles are said to be adjacent angles when they share the common vertex and side. the endpoint of the rays, forming the sides of an angle, is called the vertex of an angle. adjacent angles can be a complementary angle or supplementary angle when they share the common vertex and ...
