Since they're vertical angles, they're equal in degree measure
since they're equal, we can make the two expressions equal to each other
5a - 1 = 2a + 20
add 1 to both sides
5a = 2a + 21
subtract 2a from both sides
3a = 21
divide both sides by 3a
a = 7
now, plug the answer you found for a into one of the two expressions
5a - 1 becomes (5*7) - 1, which equals 34
to double check that they're equivalent (since they're vertical angles)
2a + 20 becomes (2*7) + 20, which equals 34
both angles are 34 degrees!
Answer:
easy 72 degree
Step-by-step explanation:
Here is the answer, I think.
First you need to change the equation to 3 < x/2 + 1
then we can treat it like a normal equation.
subtract 1 from each side to get 2 < x/2
then multiply both sides by 2 to get rid of the fraction and we have
4 < x and we switch it around to get
x > 4 as our answer! :)
First we want to find the part of the door not covered by the towel bar.
So subtract 10.25 from 26.33
In order to do this we need common denominators
So we multiply the fractions to get
(26 & 4/12) - (10 & 3/12)
Now we subtract to get
15 & 1/12
Since the 15 is odd, add 12/12 to the fraction
14 & 13/12
Now divide that in half to get the distance from each edge
7 & 13/24
