Answer:
( 7 , 4 )
Step-by-step explanation:
The variable is y
The coefficient is 4
The constant is 18
25
3x+2x+55=180
5x+55=180
5x=180-55
5x=125
X=125/5
X=25
So the value of X is 25
The remainder is 6!!
Do 180-110=70 Then have it where 70/2=35. 35+4=39, 35-4=31, so the three angles are 39, 110, and 31.
