Subtract the one value from 180 and then divide that number by 2 to get the 2 values. So if one side is 90, they other sides would be 45 each
Answer:
The sum is

Step-by-step explanation:
Assuming we are finding the sum of :
3e + 7 - e and 2e + 10 + 2e -3
Then we set up the addition as follows:

We group similar try to get:

We now combine the similar terms to obtain:

Therefore the sum is

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!
Hope this helps
Answer:
12
Step-by-step explanation:
12 beacuse We assume, that the number 48 is 100% - because it's the output value of the task.
x is the value we are looking for
Now we have two simple equations:
1) 48=100%
2) x=25%
48/x=100%/25%
Now we just have to solve the simple equation, and we will get the solution we are looking for.
Solution for what is 25% of 48
48/x=100/25
(48/x)*x=(100/25)*x - we multiply both sides of the equation by x
48=4*x - we divide both sides of the equation by (4) to get x
48/4=x
12=x
x=12
now we have:
25% of 48=12
