Question
the measure of an angle is 66.5°. what is the measure of its supplementary angle?
Step1: Definir ángulos suplementarios
Dos ángulos son suplementarios si la suma de sus medidas es 180°.
Step2: Calcular el ángulo suplementario
Sea $\theta$ el ángulo dado, entonces el ángulo suplementario $\alpha = 180^{\circ}-\theta$. Sustituyendo $\theta = 66.5^{\circ}$, tenemos $\alpha=180^{\circ}- 66.5^{\circ}=113.5^{\circ}$.
