Answer:
x=28
Step-by-step explanation:
So a triangle is 180 degrees in total then you would subtract 40 from 180 because the top angle and leaving you with 140 then divide by 5 because the bottom two getting you 28 then you could just plug in 28 for x on each angle
180-40=140
140/5=28
2(28)=56
56 is angle A
Mean is 8
you have to add all the numbers and then divide it by the number of elements you have in this case 7
Answer:
Step-by-step explanation:
The given expression is
The numerator is a quadratic trinomial and the denominator is different of two squares when 6 is factored.
We factor both the numerator and the denominator to obtain;
Cancel out the common factors to get:
This is the simplest form since, we cannot simplify this further.
