Can someone geometry is confusing

<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°

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.
