Answer:
x+113=180
Step-by-step explanation:
it's because of parallelogram property that opposite sides are parallel so being parallel this indicates co interior angle and it's sum is 180 so ,x+113=180,x=180_113,x=67 ans
Using the given information, the value of Σfd is 800
<h3>Calculating mean using Assumed mean </h3>
From the question, we are to determine the value of Σfd
The formula for mean, using the assumed mean method is given by

Where
is the mean
A is the assumed mean
From the given information,



Putting the parameters into the equation, we get





Hence, the value of Σfd is 800

Let, the number = x
Then, x * 130% = 52
x * 1.30 = 52
x = 52/1.30
x = 40
So, the number is less than 52
Hope this helps!
