Question
given that triangle abc is similar to triangle def. find the angle b.
Step1: Usar ángulos de triángulo semejante
Los triángulos semejantes tienen ángulos iguales en correspondencia. $\angle A = \angle D = 60^\circ$, $\angle C = \angle E = 79^\circ$
Step2: Suma de ángulos en triángulo
La suma de ángulos de un triángulo es $180^\circ$.
$\angle B = 180^\circ - \angle A - \angle C$
Step3: Calcular el ángulo B
Sustituir los valores conocidos:
$\angle B = 180^\circ - 60^\circ - 79^\circ$
