Answer:
n = 59°
Explanation:
Given: Angles n and (2n+3) are supplementary.
Two angles are said to be supplementary if they add up to 180 degrees.
Therefore:
[tex]n+(2n+3)=180\degree[/tex]Solve the equation for n:
[tex]\begin{gathered} n+2n+3=180 \\ 3n+3=180 \\ \text{Subtract 3 from both sides:} \\ 3n+3-3=180-3 \\ 3n=177 \\ \text{Divide both sides by 3} \\ \frac{3n}{3}=\frac{177}{3} \\ n=59\degree \end{gathered}[/tex]The value of n is 59°.
