Angles in Circles
Angles within a circle are feasible to create with the help of different properties of the circle such as radii, tangents, and chords. The radius is the distance from the center of the circle to the circumference of the circle. A tangent is a line made p…
Arcs in Circles
A circular arc is the arc of a circle formed by two distinct points. It is a section or segment of the circumference of a circle. A straight line passing through the center connecting the two distinct ends of the arc is termed a semi-circular arc.

Expert Solution & Answer
Check Mark

Answer to Problem 18RP

The measure of angleBMDis 25° .

Explanation of Solution

Given information:

  mBD⌢=90°,mAC⌢=40°.

Formula used:

The measure of secant-secant angle is one half the difference of its two intercepted arcs.

Calculation:

  Geometry For Enjoyment And Challenge, Chapter 9, Problem 18RP

The measure of angle BMD is one half the difference of arc BD and arc AC .

  m∠BMD=mBD⌢−mAC⌢2=90°−40°2=25°
