Question
find the measure of each angle.
- m∠ebg = 60°; m∠fbg = 2m∠ebf; m∠ebf =
- m∠abe = 64°; m∠dbe =
- m∠gbh = 28°; m∠gbc =
Step1: Definir variable para el ángulo
Sea $m\angle EBF = x$. Entonces $m\angle FBG=2x$.
Step2: Usar la suma de ángulos
Como $m\angle EBG=m\angle EBF + m\angle FBG$ y $m\angle EBG = 60^{\circ}$, entonces $x + 2x=60^{\circ}$.
Step3: Resolver la ecuación
Combinando términos, $3x = 60^{\circ}$. Dividiendo ambos lados por 3, $x=\frac{60^{\circ}}{3}=20^{\circ}$. Entonces $m\angle EBF = 20^{\circ}$.
