Answer:
m<L = 33; m<K = 20; m<J = 127
Step-by-step explanation:
to solve we must first figure out how much each angle is
m<L = m<K + 13
m<J = 6m<K + 7
so we add them together
m<K + m<K + 13 + 6m<K + 7 = 180
combine like terms
8m<K + 20 = 180
subtract
8m<K = 160
final answer: m<K = 20
thus: m<L = 33; m<J = 127
