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!
We can find an unknown side in a right-angled triangle when we know:one length, and one angle (apart from the right angle).Example: Depth to the Seabed The ship is anchored on the seabed. We know: the cable length (30 m), and the angle the cable makes with the seabed So we ...
In the right—;angled triangle (with the right angle in ) the angle bisectors of the acute angles intersect at point . The distance of to the hypotenuse is . What is the distance of to ? A: B: C: D: E: 相关知识点:
In a right triangle, the side opposite the right angle is called the ___. A. hypotenuse B. leg C. base D. height 相关知识点: 试题来源: 解析 A。在直角三角形中,直角所对的边叫斜边“hypotenuse”;“leg”是直角边;“base”是底边;“height”是高。所以选 A。 反馈 ...

In a right triangle, if one angle is 45 degrees and one side is 5, what is the length of the other side? A. 5 B. 5√2 C. 10 D. 5√3 相关知识点: 试题来源: 解析 A。因为是 45 度的直角三角形,所以两直角边相等,所以另一条直角边也是 5 。
In a right triangle, one acute angle is 30°, then the other acute angle is: A. 30° B. 45° C. 60° D. 90° 相关知识点: 试题来源: 解析 C。因为直角三角形两锐角之和为 90°,一个锐角为 30°,所以另一个锐角为 90° - 30° = 60°。反馈 收藏 ...
The side with the smallest length D. The side adjacent to the right angle 相关知识点: 试题来源: 解析 A。在直角三角形中,“hypotenuse”(斜边)是最长的边。B 选项,斜边不是对着最小角的边;C 选项,斜边不是最短的边;D 选项,斜边不是邻着直角的边。反馈 收藏 ...
In a right triangle, if one acute angle measures 30 degrees, what is the measure of the other acute angle? A. 30 degrees B. 45 degrees C. 60 degrees D. 90 degrees 相关知识点: 试题来源: 解析 C。在直角三角形中,两个锐角之和为 90 度。已知一个锐角为 30 度,所以另一个锐角为 90...
