Find the missing sides of the triangle. Show Solution The angle of elevation to the top of a building in Chicago is found to be 9 degrees from the ground at a distance of 2000 feet from the base of the building. Using this information, find the height of the building. Glossary adjacen...
It sounds like your problem is asking you to try to find angle B in a triangle with a = 40, b = 80, and A = 60 degrees. Try constructing such a triangle, and see what happens. We make angle A and mark 80 units on one of its rays for side b, then swing an arc around...
Answer to: Refer to the right triangle ABC with C = 90 degrees. Use the given information to find the six trigonometric functions of A. b = 8, c =...
A30 60 90 triangleis a special right triangle with 30° and 60° interior angles adjacent to the right 90° angle. Leg a Given the length of legb(the side opposite the 60° angle), the formula to find the length ofais: a =b ×√3/3 ...
A right triangle is triangle with an angle of 90 degrees (pi/2 radians). The sides a, b, and c of such a triangle satisfy the Pythagorean theorem a^2+b^2=c^2, (1) where the largest side is conventionally denoted c and is called the hypotenuse. The ot
A. 30 degrees B. 60 degrees C. 90 degrees D. 150 degrees 相关知识点: 试题来源: 解析 B。在直角三角形中,两个锐角之和为 90 度。已知一个角为 30 度,所以另一个锐角为 90 - 30 = 60 度。选项 A 仍是 30 度,不符合;选项 C 是直角的度数;选项 D 超过了 90 度,不是锐角。
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。解析:直角三角形两个锐角和为 90 度,一个锐角为 30 度,另一个锐角为 90 - 30 = 60 度。
A triangle has sides with lengths of 63 feet, 65 feet, and 16 feet. Is it a right triangle? How to Identify a Right Triangle: Any triangular shape in which two side lengths have an angle of {eq}90^{\circ}, {/eq} is called a right triangle. Right ...
A right triangle has one angle of 90 degrees. The other two angles are ___. A. acute B. obtuse C. right D. reflex 相关知识点: 试题来源: 解析 A。本题考查直角三角形的性质和角的分类。直角三角形有一个角是 90 度,剩下的两个角之和为 90 度,所以是锐角(acute)。B 选项 obtuse 是钝角...
