To find: the value of m∠A .

Expert Solution & Answer

Answer to Problem 1ST2

The value of m∠A=40 .

Explanation of Solution

Given information:

Given figure,

McDougal Littell Jurgensen Geometry: Student Edition Geometry, Chapter 9.7, Problem 1ST2

MD↔ is tangent to the circle.

If marcBD=80

Calculation:

The measure of an inscribed angle is equal to half the measure of its intercepted arc. Therefore,

m∠A=12marcBD=12⋅80=40

Therefore, the value of m∠A=40 .
