Question

find the measure of each angle.

  1. m∠ebg = 60°; m∠fbg = 2m∠ebf; m∠ebf =
  2. m∠abe = 64°; m∠dbe =
  3. m∠gbh = 28°; m∠gbc =

Explanation:

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 $m\angle EBF = 20^{\circ}$.

Answer:

$m\angle EBF = 20^{\circ}$
