Answer:
72
Step-by-step explanation
48 + k+l =180
48 +90+l =180
138 +l = 180
l=180 - 138
l = 42
now
l+m+n= 180
42 +m+66 =180
108+m= 180
m= 180 -108 m =72

I’m sorry I don’t know the answer I wish I could help
Step-by-step explanation:
x = 113
Since the shape is a quadrilateral, the angles add up to 360 so:
x + 87 + 113 + 47 = 360
x + 247 = 360
x = 360 - 247
88
