Answer:
x=15 degree
Step-by-step explanation:
5x +5+6x -1+3x+5x+3+4x+8 =360 degree (exterior angles of pentagon is 360 degree)
23x +15 =360
23x=360-15
x=345
x=345/23
x=15 degree

The area would be 132cm^2 (squared)
(9x4)x2+(7+8)x4 =132
The perimeter you just add everything up so it’s 65cm
15+13+4+7+9+4+13
