Answer:
<h2>m∠1 = 100°, m∠2 = 80°</h2>
Step-by-step explanation:
We know: Supplementary angles add up to 180°.
Therefore
m∠1 + m∠2 = 180° → m∠2 = 180° - m∠1 (*)
We have

Substitute (*):
<em>cross multiply</em>
<em>use the distributive property</em>

<em>add 5m∠1 to both sides</em>
<em>divide both sides by 9</em>

the answer is none of them because if you do 0.09 as fraction, it will be 9/100 and you cant simplify that
