The angles of a triangle are (3x) , (2x - 7) and (4x - 11). Then, x =
Answers
Answer:
3x = 0
x =0/3=0
x=0
2x-7=0
2x = 0-7=-7
x = -7/2
4x -11=0
4x =0-11=-11
x =-11/4
Answer:
Step-by-step explanation: Perimeter of triangle = sum of three sides 180 = 3x + 2x-7 + 4x-11 180 = 3x + 2x + 4x - 18 [3+2+4]x = 180+18 9x = 198 x = 198 divide 9 x = 22
First side is 3x = 3*22 = 66, Second side is 2x - 7 = 2*22 - 7 = 37 and Third angle is 4x - 11 = 4*22 - 11 = 77
