Question

I need to know if A and B are CORRECT and I need HELP WITH C

Answer 1

- The theorem we shall apply here is that "The sum of angles in a triangle is 180 degrees."

Question C:

`\begin{gathered} 24+x+x=180\degree\text{ (Sum of angles in a triangle)} \\ 24+2x=180 \\ \text{Subtract 24 from both sides} \\ 2x=180-24 \\ 2x=156 \\ \text{Divide both sides by 2} \\ (2x)/(2)=(156)/(2) \\ \\ \therefore x=78\degree \end{gathered}`

Final Answer

The value of x is 78
