Question

Find BR if D is the circumcenter of triangle ABC, CD=11.1, and RD=5.2. Round to the nearest tenth.

Answer 1

To find BR, subtract RD from CD, given CD = 11.1 and RD = 5.2.

Step-by-step explanation:

To find the length of BR, we need to use the properties of a circumcenter. In a triangle, the circumcenter is the point of intersection of the perpendicular bisectors of the sides. Since D is the circumcenter, CD is the radius of the circumcircle. Therefore, CD is equal to the distance from D to any vertex, such as B. Given that CD = 11.1 and RD = 5.2, we can subtract RD from CD to find the length of BR.

BR = CD - RD = 11.1 - 5.2 = 5.9 (rounded to the nearest tenth).
