I need help. Because is an important homework.​

i write everything in the exploration

Step-by-step explanation:

MN=31

KN=45

K=61°

L=119°

M=61°

CF=10

FE=15

CE=14

GD=11

QR=19

SR=24

PT=21

SQ=20

QRS=70°

PQS=53°

RPS=35°

PSQ=53°

7x-2=12x-22

-2=5x-22

20=5x

x=4

7×4-2=26 (12×4-22=26)

(2x+11)×2=8x-14

4x+22=8x-14

22=4x-14

36=4x

x=9

( (2×9+11)×2=58. 8×9-14=58. so it's correct)

(3x+5)+(9x-17)=180

12x-12=180

12x=192

x=16

( (3×16+5)+(9×16-17)=53+127=180 so it's correct)

10x-27=2x+29

8x-27=29

8x=56

x=7

10×7-27=43 (2×7+29=43)

V=180-43°=137°
