A=x
B=3x-2
C=y
A/Q,
y-3x+2=9
y-3x=7
y= 7+3x
A+B+C= 180
x+3x-2+y= 180
x+3x-2+7+3x= 180
7x+5=180
7x= 175
x= 25
Thus,
You can now find the angles by putting value of x.
B=3x-2
C=y
A/Q,
y-3x+2=9
y-3x=7
y= 7+3x
A+B+C= 180
x+3x-2+y= 180
x+3x-2+7+3x= 180
7x+5=180
7x= 175
x= 25
Thus,
You can now find the angles by putting value of x.
Yacika:
The value of X is a 25. As per day ans given in book
Sorry, it will be 7x+5=180, correct that minus sign and you will get the answer as 25, enjoy!
Please mark as brainliest if it helped.
