What is the adjacent side of a triangle? How is a rectangle a convex quadrilateral? What is the greatest value of the sum of the digits of the number made from the sum of the digits of a three digit number? Explain total internal reflection. ...
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。
Adjacent angles and vertical angles are the pair of angles, in geometry. Adjacent angles have common vertex and common arm. Vertical angles have common vertex. Learn how to solve adjacent angles with examples.
For example, if one side of an equilateral triangle is 4 inches long, then all three sides measure 4 inches and the perimeter would be 12 inches (4 x 3). Similarly, if you know all three side lengths, you can calculate its area using Heron’s formula or another similar equation. ...
Exterior angles: Exterior angles are the angles formed outside a shape, between any side of a shape and an extended adjacent side. Here, ∠ACD is an exterior angle.Complementary and Supplementary Angles:Complementary angles: Angles that add up to 90° (a right angle) are called complementary ...
The altitude of an equilateral triangle ABC is: {eq}h=15 {/eq}. Let us assume that {eq}x {/eq} is the side of the triangle ABC. The relation...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a...
In trigonometry, the tangent of an angle of a triangle is defined as the ratio of the length of the opposite side to the length of the adjacent side. The triangle is formed by the rays of two radii from the center of a circle. The first ray forms the base of the triangle, and the...

In geometry, a square is a regular quadrilateral, which means that it has four equal sides and four equal angles (90-degree angles, or 100-gradian angles or right angles). It can also be defined as a rectangle in which two adjacent sides have equal length. Triangle The plane figure form...
