an equation is undefined, when its denominator is 0, or turns to 0, because we can't divide anything by 0.
so let's simply set the denominator of this one = 0.

Answer:
43°
Step-by-step explanation:
<h2>
<u>Equation:</u></h2>
<u />
m∠ABD = m∠1 + m∠2
Substitute:
68° = m∠1 + (m∠1 + 18°)
<h2>
<u>Solve:</u></h2>
68° = m∠1 + (m∠1 + 18°)
68° = 2(m∠1) + 18°
50° = 2(m∠1)
25 = m∠1
<h2>
<u>Solution:</u></h2>
<u />
Know that we know that m∠1 is, we can add 18* to find m∠2
25° + 18° = 43°
