Answer: 80

Explanation:

  • m + 20 = 100 [vertical angles are congruent]
  • m = 80 [subtract 20 from both sides]

\huge\textbf{Hey there!}


\huge\textsf{\bf{A}}\huge\text{ssuming ....}


\mathsf{m + 20^\circ = 100^\circ}


\huge\textbf{I}\huge\text{f so, then let's solve for your answer to your}\\\huge\text{given equation.... shall we?}


\mathsf{m + 20^\circ = 100^\circ}


\mathsf{m + 20 = 100}


\huge\textbf{S}\huge\text{ubtract 20 to BOTH SIDES}


\mathsf{m + 20 - 20 = 100 - 20}


\huge\textbf{S}\huge\text{implify it!}


\mathsf{m = 100 - 20}


\mathsf{m = 80}


\huge\textbf{T}\huge\text{herefore, your answer is: \boxed{\mathsf{m = 80^\circ}}}\huge\checkmark


\huge\textbf{G}\huge\text{ood luck on your assignment \& enjoy your day!}
