Answer:
84
Step-by-step explanation:
sum of interior angles of a pentagon is 540. A triangle is 180, then for each side you add another 180, so a square would be 360 and a pentagon is 540
Sum up all given sides
131+108+107+110=456
subtract this number from 540
540-456=84
x degree= 84

Step-by-step explanation:
How to Calculate the Semi Interquartile Range / Quartile Deviation. As the SIR is half of the Interquartile Range, all you need to do is find the IQR and then divide your answer by 2. Note: You might see the formula QD = 1/2(Q3 – Q1). Algebraically they are the same.
