Question 221104: find the masurement of each angle in the triangle.
(6n+31)
(5n-19)
(n+12)
now i tired 5n-19=180
-19+19=0
180+19=199
5n=199
5n*5=0
199*5=39.8
saying that my answer is 39.8
but i know this is wrong because it's multiple choice and it didnt fit so i didnt do the other ones yet

find the masurement of each angle in the triangle.
(6n+31)
(5n-19)
(n+12)
-------------
I suppose those are the 3 angles ??
If so, they add up to 180º
12n + 24 = 180
12n = 156
n = 13
-------
Sub for n to find the 3 angles
109º
46º
25º

Remember, all angles in a triangle add to 180 degrees. This means %286n%2B31%29%2B%285n-19%29%2B%28n%2B12%29=180


%286n%2B31%29%2B%285n-19%29%2B%28n%2B12%29=180 Start with the given equation.


6n%2B31%2B5n-19%2Bn%2B12=180 Remove the parenthesis.


12n%2B24=180 Combine like terms on the left side.


12n=180-24 Subtract 24 from both sides.


12n=156 Combine like terms on the right side.


n=%28156%29%2F%2812%29 Divide both sides by 12 to isolate n.


n=13 Reduce.



Now just plug this value into the given angles to get:

6n%2B31=6%2813%29%2B31=78%2B31=109


5n-19=5%2813%29-19=65-19=46


n%2B12=13%2B12=25


So the three angles are 109, 46, and 25 degrees.
