CAN YOU HELP ME PLEASE

1) angle NMP=103 and angle LMP=77

2) angle QST=58 and angle RSQ=32

Step-by-step explanation:

1)  can find the angle NMP:

180-(-20x+13)=(-16x+23)

180+20x-13=-16x+13

180-13-23=-16x-20x

144=-36x

x=-4

angle NMP: 180-(-16*(-4)+13) = 103

angle LMP: 180-103 = 77

2) can find the angle QST:

90-(15x-43)=(8x+18)

90-15x+43=8x+18

90+43-18=8x+15x

115=23x

x=5

angle QST: 90-(15*5-43)=90-(75-43)=58

angle RSQ: 90-58=32

the one below it is a function

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
