26 – x = 14. what is x
Answer:
x=12
Step-by-step explanation:
start with this equation:
26-x=14
it's best to make the x variable positive at all times.
to do that, you need to make everything else positive.
-26+x=-14
then add 26 to both sides.
x=-14+26
which basically says 26-14...
x=12

dexter needs to find each angle in this figure that is adjacent to (the second question)
The Adjacent angle to <LON are <NOP, <NOK and <LOK.
What are adjacent angle?When two angles share a shared vertex and side, they are said to be neighbouring angles. The vertex of an angle is the terminal of the rays that create the sides of an angle. When two adjacent angles have a common vertex and side, they might be complimentary or supplementary angles.
Now, the adjacent angle to <LON are <NOP, <NOK and <LOK.
Dexter claim is wrong because <MON is not adjacent to <LON, <MON is just a part of <LON.
and, the part of an angle cannot be considered as Adjacent angle.
