Question

What is the measure of minor arc `ED`, What is the measure of angle `ACD`, What is the measure of the major arc `ABD`, What is arc `BAD` called, and What is the measure of arc `BAD`?

Answer 1

Solution

Minor Arc ED

$Minor\text{ Arc ED=43}^0(vertically\text{ opposites\rparen}$

Angle ACD

$\begin{gathered} 43+ACD=180(supplementary\text{ \rparen} \\ \\ ACD=137^0 \end{gathered}$

Major arc ABD

$180+43=223^0$

Arc BAD is called Semicircle

The measure of Arc BAD

$180^0\text{ \lparen sum of angle is semicircle\rparen}$
