Question
c. use your algebra skills to find the angle measurements. 13) a) find the value of x. b) m∠mht = __ c) m∠ahm = __
Step1: Ángulos suplementarios, igualar a 180°
Los ángulos $\angle AHM$ y $\angle MHT$ forman un ángulo llano, así que:
$$(2x+11) + (6x-7) = 180$$
Step2: Simplificar la ecuación
Combinar términos semejantes:
$$8x + 4 = 180$$
Step3: Despejar el término con $x$
Restar 4 de ambos lados:
$$8x = 176$$
Step4: Calcular el valor de $x$
Dividir entre 8:
$$x = \frac{176}{8} = 22$$
Step5: Calcular $m\angle MHT$
Sustituir $x=22$ en $(6x-7)$:
$$m\angle MHT = 6(22) - 7 = 132 - 7 = 125$$
Step6: Calcular $m\angle AHM$
Sustituir $x=22$ en $(2x+11)$:
$$m\angle AHM = 2(22) + 11 = 44 + 11 = 55$$
