Answer:
[tex]a = 278^{\circ}[/tex]
Step-by-step explanation:
Given
[tex]b = 22^{\circ}[/tex]
[tex]Whole\ Angle = 300^{\circ}[/tex]
Required
Find the measure of a
Since there is no diagram to support the question, we'll assume that:
[tex]a + b = Whole\ Angle[/tex]
This gives:
[tex]a + 22^{\circ} = 300^{\circ}[/tex]
Subtract 22 from both sides
[tex]a + 22^{\circ}-22^{\circ} = 300^{\circ}-22^{\circ}[/tex]
[tex]a = 300^{\circ}-22^{\circ}[/tex]
[tex]a = 278^{\circ}[/tex]
