Question

angle relationships
classify the angles
m j n (with arrows on m and n, and a point k on a ray from j)
linear pair
vertical angles
boom cards
m∠kjm = 65°
find m∠kjn.
(input box with ° symbol)

Explanation:

Step1: Identify angle relationship

Los ángulos $\angle KJM$ y $\angle KJN$ forman un par lineal, por lo que suman $180^\circ$.

Step2: Calculate $\angle KJN$

$$m\angle KJN = 180^\circ - m\angle KJM$$
Sustituimos el valor dado:
$$m\angle KJN = 180^\circ - 65^\circ$$

Step3: Compute the result

$$m\angle KJN = 115^\circ$$

Answer:

Relación de ángulos: Linear Pair
$m\angle KJN = 115^\circ$
