Two supplementary angles have measures m∠ABC=105° and m∠CBD=(3x−24)° . What is the equation to solve for x ? (1 point)
The sum of supplementary angles is 180°, so we have the equation:
m∠ABC + m∠CBD = 180°
Substituting the given angle measures, we have:
105° + (3x-24)° = 180°
Simplifying the equation gives:
3x + 81° = 180°
Now we can solve for x.
