In ΔLMN, n = 430 inches, m = 340 inches and ∠M=158°. Find all possible values of ∠N, to the nearest 10th of a degree.

correct answers below:

80 the answer is 80

step-by-step explanation:

c

-by-step explanation:

it would be c

m∠abd = m∠dbc

step-by-step explanation:

given : ab bisects ∠dbc

as we know that bisection means ab divides   ∠dbc   in two equal angles named as   ∠dba and   ∠abc

so, m∠abd = m∠dbc  

because ab bisects ∠dbc.

hence , the first statement m∠abd = m∠dbc is true.
