In an obtuse angle triangle, the sum of the squares of the two sides is less than the square of the longest side. For example, if the sides of an obtuse triangle measure a, b, and c such that c is the largest side, then we have: a2+ b2< c2. Conversely, if in a triangle, if...
An obtuse angle is greater than ___ degrees and less than 180 degrees. A. 90 B. 120 C. 150 D. 180 相关知识点: 试题来源: 解析 A。本题考查钝角的定义。钝角是大于 90 度小于 180 度的角,B、C 选项的度数不是钝角的界定范围,D 选项 180 度是平角。反馈 收藏 ...
We show that in the special case where the maximal angle between the cones is nonobtuse, it does suffice to check only the generators. This special case can be checked at essentially no extra cost, and we incorporate that information into an improved algorithm to find the maximal angle....

SAXS, small-angle X-ray scattering. We then used MultiFoXS with our high-resolution structure of the Sas20d1 domain and model of Sas20d2 in isolation to investigate how the domains are positioned relative to each other. The best model fit was a three-state ensemble with an acceptable χ2...
A. an acute B. a right C. an obtuse D. a straight相关知识点: 试题来源: 解析 A If we subtract an acute angle from 180∘, we get an acute angle. 钝角的补角是( )角. A.锐角 B.直角 C.钝角 D.平角 如果我们从180∘减去钝角,得到锐角. 故选A.反馈...
athrough a 3D numerical analysis. It was found that the affected area along the main tunnel, which requires addi-tional support work, is about one tunnel diameter on the obtuse angle side and about three tunnel diameters on the acute angle side from the point of intersection. The practice ad...
is formed in the contact housing. The handle has a tilting surface defining a tilting axis that is inclined with respect to the pin at an obtuse angle which is greater than 110 degree. The tilting axis is formed by an edge between the tilting surface and a contact surface of the handle....
