Step-by-step explanation:
m = 14, n = 12.5
m<L = (5m + 36)° = (5(14) + 36)°
L = 106°
m<p= (6n-1°)=(6x12.5-1°)
p=74°
m<Q = (4m + 50)° = (4(14) + 50)°
Q = 106°
k=360°-(106°+74+°106°)=360°-286°
k=74°
The sum of the interior angle of a parallelogram is 360°
The opposite side of a parallelogram are equal.
