The measure of angle CBD is given as (3×-24)°. We can simplify this expression:
(3×-24)° = -72°
Since angle ABC and angle CBD are supplementary, their measures add up to 180°:
m ABC + m CBD = 180°
Substituting the given measures:
105° + (-72°) = 180°
Combining like terms:
33° = 180°
Since the equation 33° = 180° is not true, it does not need to be solved for x.
Two supplementary angles have measures m ABC = 105° and m CBD = (3×-24)°. What is the equation to solve for x?
