To find the total surface area of a cone, we can use the formula: Total Surface Area=πrl+πr2 where:- r is the radius of the base of the cone,- l is the slant height of the cone,- π is a constant (given as 227). Step 1: Identify the given values- Radius r=21 cm- Heig...
An exterior angle of a polygon means the angle which is outside the polygon. The sum of the exterior angles of any polygon is 360 degrees. To find the measure of an exterior angle of a regular polygon, we divide 360 by the number of sides of the polygon....
A circle could be circumscribed about the quadrilateral with angle measures 120 90 90 and 60?Polygons which can be constructed entirely from the repetition of a single length of line segment are called regular polygons?Is 0.01 equal 0.1?What is a circumcenter of a triangle?
In a triangle, if the angle is 45 degrees and the adjacent side is 5√2, what is the length of the opposite side? A. 5 B. 5√2 C. 5√3 D. 10 相关知识点: 试题来源: 解析 B。因为是 45 度角,所以正切值为 1,即对边/相邻边 = 1,所以对边 = 相邻边 = 5√2。
Two bugs start simultaneously () from A and crawl(爬 ) along the sides of the triangle in opposite directions at the same speed. They meet at point D. What is B D ?()D飞6A B5(A)1(B)2(C)3(D)4696. The measure (尺寸) of angle A B C is 50° , A D bisects (平分) angle...
What is a triangle with one right angle called?Right Angles:A right angle is an angle of 90 degrees. All right angles are exactly the same. The corners of a rectangle and a square are all comprised of right angles. Because a right angle can be seen as a quarter of a complete turn,...
Answer to: Consider the triangle shown in the diagram below. Suppose that m angle A = 83 degrees, m angle C = 34 degrees, and c = 41.8. What is the...
The Reuleaux Triangle shows the sharpest angle between the vertex of any shape that has a curve of constant width. Each pair of the arc makes an angle of 120°. The Reuleaux Triangle can be used as a rotor within a square; it can perform a complete rotation and stay inside the square ...
