(14) find the m∠abc and m∠cbd. show your work and include the units.
triangle with a, b, c, d (d on extension of ab), ∠a=63°, ∠c=79°
Step1: Calcular \( m\angle ABC \)
En un triángulo, la suma de los ángulos internos es \( 180^\circ \). En \( \triangle ABC \), conocemos \( \angle A = 63^\circ \) y \( \angle C = 79^\circ \). Entonces:
Step2: Calcular \( m\angle CBD \)
Los ángulos \( \angle ABC \) y \( \angle CBD \) son ángulos suplementarios (forman una línea recta), por lo que su suma es \( 180^\circ \). Entonces:
