Answer:
Step-by-step explanation:
β ∈ { 0° , 18° , 180° , 198° }
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°
Give me branliest sir I have the answer ready for you
First find the mean (sum divided by number of values)
4+5+8+10+15=42
42/5=8.4
Then find the difference between each of the numbers and the mean.
4.4, 3.4, 0.4, 1.6, 6.6
Then find the mean of those values.
4.4+3.4+0.4+1.6+6.6=16.4
16.4/5=3.28
Final answer: 3.28
