I need to know x is exactly
So angles on a straight line add up to 180°
And angles in a triangle adds up to 180° try if you can work it out now
If you still don’t understand let me know
Answer:

Step-by-step explanation:
,
,
, Subtract 23 and 3x from both sides and simplify:
, Divide both sides by 2 and simplify: 
<em>Hope this helps!!!</em>
Y=1/2x+6
Y-2=1/2(x+8)
Then simplify and get y by itself
Answer:
#1 - Two complementary angles with measures that have a sum of 90.
#2- angles with a common vertex and side.
#3 - two supplementary angles with measures that have a sum of 180.
#4 - the region of a plane inside an angle
#5 - the region of a plane outside an angle
#6 - an angle with a measure of anything less than 90 degrees.
#7 - an angle with a measure of anything greater than 90 degrees.
These all should be right :)
Lmk how I did!
