Given:
The given sets are:
Set a : 200, 104, 100, 160.
Set b: 270, 400, 483, 300, x.
Mean of set a: mean of set b= 3:8
To find:
The value of x.
Solution:
Formula for mean:
The mean of set of a is:
The mean of set of b is:
It is given that,
Mean of set a: mean of set b= 3:8
Isolate the variable x.
Divide both sides by 3.
Therefore, the value of x is 427.
<u>Answer:</u>
The angles measures x and 4x are complementary angles. The value of x is 36 degrees
<u>Solution:</u>
Given, two angles are x and 4x
We have to find the value of above given x
We are also given that, given two angles are complementary angles for each other
So, we know that, <em>sum of any two complementary angles will always be equal to 180 degrees </em>
Then, in the problem given,
Hence the angles measures x and 4x are complementary angles. The value of x is 36 degrees
