Answer:
Angles of a triangle add up to <u>180 degrees. </u>
<u />
So, if we add up all three of the angles of this triangle, we should have a sum of 180 degrees.
4x-10+x+26+x+14=180
4x-10+2x+40=180
6x+30=180
6x=150
x=25
Let me know if this helps!
C)55,556 take 500 x 1,000 and get 500,000 then devide by 9 to get 555.5555556 round to 55,556 plz mark brainliest! :)
You know the solution to the system is equal because it's a number equals to the same number
Answer:
a=21
b=25/2
c=77/2
Step-by-step explanation:
from eq 1
a+4=2b => a=2b-4
substituting value of a in eq 2
c-5=a+b => c-5=2b-4+b => c =3b+1
now, substituting value of a and c in eq 3
a+b+c=72 => 2b-4+b+3b+1 =72 => 6b-3=72 => b= 75/6 => b=25/2
substituting value of b in :
c=3b+1 ( you will get c )
then substitute value of b in :
a=2b-4 ( to get a)
