Answer:

La medida del ángulo de la abertura menor es 29°.      

Step-by-step explanation:

Podemos calcular la medida del angulo de la abertura menor hallando el valor de "x" en la siguiente ecuación:

(x + 5) + (2x + 13) = 90   (1)

Dado que en la figura podemos observar que la suma de ambos ángulos de abertura resulta en un ángulo rectángulo.

Al resolver la ecuación (1) tenemos:                                  

x + 2x = 90 - 13 - 5

3x = 72

x = 24

Ahora, podemos encontrar los ángulos de abertura.

Angulo de abertura menor:

x + 5 = 24 + 5 = 29^{\circ}

Angulo de abertura mayor:

2x + 13 = 2*24 + 13 = 61^{\circ}

Por lo tanto, la medida del ángulo de la abertura menor es 29°.

Espero que te sea de utilidad!

What is the exterior angle?
olganol [36]

Answer:

angle YUT = 120

Step-by-step explanation:

in Triangle SUT

angle 70 + angle 50 + angle x = 180

 70 + 50 + x = 180

 120 + x = 180

 x = 180 - 120

 x = 60

angle SUT = 60



angle SUT + angle YUT = 180 ( straight line)

60 + x = 180

 x = 120


Therefore angle YUT ( exterior angle ) = 120
