What type of angle is a 17∘angle? Classifying Angles by Their Measures In geometry, we can classify angles using their measures. That is, if an angle is between 0° and 90°, we call it an acute angle, If an angle is between 90° and 180°, we call it an obtuse angle, and ...
What is the measure of a straight angle? A. 90 degrees B. 180 degrees C. 360 degrees D. 270 degrees 相关知识点: 试题来源: 解析 B。解析:straight angle 是平角,平角的度数是 180 度。选项 A90 度是直角的度数;选项 C360 度是周角的度数;选项 D270 度不是平角的度数。
The ramp has an angle of 30 degrees. What is the meaning of “angle” in this case? A. gradient B. speed C. distance D. time 相关知识点: 试题来源: 解析 A。“angle”在这种情况下指的是坡度,选项 A“gradient”有坡度的意思;选项 B“speed”是速度;选项 C“distance”是距离;选项 D“...
What is the measure of the other angle? A. 55 degrees B. 65 degrees C. 45 degrees D. 35 degrees 相关知识点: 试题来源: 解析 A。直角为 90 度,一个角是 35 度,那么另一个角是 90 - 35 = 55 度。选项 B 65 度错误;选项 C 45 度错误;选项 D 35 度错误。 反馈 收藏 ...
题目Two angles are complementary. One angle is 30 degrees. What is the measure of the other angle? A. 60 degrees B. 45 degrees C. 30 degrees D. 150 degrees 相关知识点: 试题来源: 解析 A。互补角之和为 90 度,一个角为 30 度,另一个角为 90 - 30 = 60 度。
If an angle measures 180 degrees, what is it? A. Acute angle B. Right angle C. Obtuse angle D. Straight angle 相关知识点: 试题来源: 解析 D。180 度的角是平角,选 D。选项 A 锐角小于 90 度,选项 B 直角是 90 度,选项 C 钝角大于 90 度小于 180 度。反馈 收藏 ...
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) + ...
