Answer:
The value of x is 108°
Step-by-step explanation:
Given interior angles of parallelogram are:

<u>The sum of interior angles of a parallelogram is 360°.</u>
We will use this information to find the value of x.
So adding up all the angles and putting the sum equal to 360 we get,


Taking LCM on left side of the equation, as it involves fraction

Multiplying both sides by 3

Dividing both sides by 10

Hence,
The value of x is 108°
Answer:
Each person shared 1/6 of the cake.

Answer:
r=20
Step-by-step explanation:
since the angle and sum of a straight line is equal to 180, you structure an equation:
180=105+(4r-5)
solve for r
180=100+4r
80=4r
20=r
check answer
4r-5 4(20)-5
80-5
75+105=180

Answer:
8.7
Step-by-step explanation:
To find the mean first you have to add up all the weight of the cats which is:
After, you have to divide the total weight by the number of cats there are
which is: 
Since, this is a really long number you would normally round the number to the nearest tenth which is 8.7
