WebThis formula tells us the shortest distance between a point (𝑥₁, 𝑦₁) and a line 𝑎𝑥 + 𝑏𝑦 + 𝑐 = 0. Since the radius is perpendicular to the tangent, the shortest distance between the center and the tangent will be the radius of the circle. 𝑥 = 5 This can be rewritten as: 𝑥 - 5 = 0 Fitting this into the form: 𝑎𝑥 + 𝑏𝑦 + 𝑐 = 0 We see that: 𝑎 = 1 𝑏 = 0 WebOct 14, 2024 · Answer: length of BC = 5 cm Step-by-step explanation: ΔDOC ∠DOC= 60° & OC = OD ( Radius) => ∠OCD = ∠ODC = 60° => ΔDOC is Equilateral triangle with side = radius ∠ACD = 90° (inscribed angle by diameter) => ∠OAC = 180° - 90° - 60° = 30° AC² + CD² = AD² => AC² + R² = (2R)² => AC = √3 R ∠OAC = 30° ∠OBA =60° => ∠AOB = 90° Draw CE ⊥ AD

Web5 In the accompanying diagram of circle O, diameter AB is perpendicular to chord CD and intersects CD at E, AE =9, and EB =4. What is ED? 1) 8 2) 7 3) 6 4) 4 6 In the diagram below of circle O, diameter AB is perpendicular to chord CD at E. If AO =10 and BE =4, find the length of CE. 7 In the accompanying diagram of circle O, diameter WebIn circle O, AD and BE are diameters. What is mAE? Solution: ∠AOB = ∠EOD = 3x (As they are vertically opposite angles) ∠AOB + ∠BOC = 90, i.e. 3x + 0.5x + 34 = 90. 3.5x + 34 = 90 . By … powerball winning nbs powerball numbers

Add a comment 2 Answers WebCircle In geometry, a circle is a closed curve formed by a set of points on a plane that are the same distance from its center O. That distance is known as the radius of the circle. Diameter The diameter of a circle is a line segment that passes through the center of the circle and has its endpoints on the circle. towhidul alam
