Answer:

According to the angle addition postulate, if B lies on AC, than AB+BC=AC.

We can use this to create this equation.

x+12+2.4=26 Where x+12 is the value of AB and 2.4 is BC.

The next step is to combine like terms, so we add 12 to 2.4 to get

x+14.4=26. When trying to find the value of a variable, you must isolate it. To do this for this equation, we must subtract 14.4 from both sides which will give you.

x=11.6

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!

42.5 I think

3x+10+x=180
4x=170
170/4=x
X=42.5
