We can find anunknown anglein aright-angled triangle, as long as we know the lengths oftwo of its sides. Example The ladder leans against a wall as shown. What is theanglebetween the ladder and the wall? The answer is to useSine, Cosine or Tangent!
cosecant In trigonometry, a function of an angle in a right-angled triangle found by dividing the length of the hypotenuse( the longest side ) by the length of the side opposite the angle. Thus the cosecant of an angle A,usually shortened to cosec A , is always greater than(or equal ...
right angle是名词,直角,triangle是三角形,也是名词, 所以在形容直角三角形时,实际上是指直角的三角形,因此需要变成形容词 在angle后面加d,就是把直角变成直角的 分析总结。 所以在形容直角三角形时实际上是指直角的三角形因此需要变成形容词结果一 题目 right angled triangle 为什么angle后加个dright angle 不就是...
