The two cases are :
or
- a -4 = 0, that leads to a = 4
We can conclude :

<LMP and <NMP are supplementary angles so sum = 180
<LMP + <NMP = 180
(-16x + 13) + ( - 20x + 23) = 180
-16x + 13 - 20x + 23 = 180
-36x + 36 = 180
-36x = 144
x = -4
<LMP = -16x + 13 = -16(-4) + 13 = 77
<NMP = - 20x + 23 = - 20(-4) + 23 = 103
Answer
<LMP = 77°
<NMP = 103°
Answer: i will put the answer as a comment but what are you rounding to
Step-by-step explanation:
The answer you're looking for is, x = 3,-5
