The hoe has a blade (40) with rounded edges which meet in a point. It is fastened at an angle of more than 90[deg] to a handle (20) by a sleeve (30) attached to it which is screwed in place.
因表示的是一般事实,要用一般现在时,关系代词which的先行词angle是单数,谓语动词也用第三人称单数形式,measure意思为"尺寸是..."时是不及物动词,没有被动语态。B项正确。故选:B。【思路点拨】测量180度的角叫做平角。其他角包括锐角、钝角、直角和周角。【解题思路】解答此类问题要了解各种时态的基本含义,并区别...
An angle which is greater than 0∘ and less than 90∘ is called acute angle. And an angle which is greater than 90∘ and less than 180∘ is called obtuse angle.Answer and Explanation: (a) Given: The given angle is −π6. The objective ...
One angle of an obtuse triangle is four times the first angle, while the third angle is 30 degrees less than the first angle. What are the degree measures of the three angles? Is the sum of two acute angles sometimes, always, or never an obtuse angle? Two angles of an obtuse triangle...
其他角度包括锐角、钝角、直角和周角。分析句子可知,此空应填从句的谓语动词,且这里measure表 “ (尺寸、长短、数量等)量度为 ” 时,所以应用主动形式,再根据句意可知,时态应用一般现在时表客观事实,从句的先行词为The angle ,为第三人称单数,所以谓语也应用第三人称单数形式。故选B项。 反馈 收藏 ...
