Answer:
The angles of the triangle are 3x, 2x−7 and 4x−11
Sum of the angles of triangle = 180
3x+2x−7+4x−11=180
9x−18=180
9x=198
x=22
∘
Thus, the angle are 66
,37
and 77
Step-by-step explanation:
Hi Unnie! I hope it helps you!(◍•ᴗ•◍)
Sum of angles of triangle is 180∘
3x+(2x−7)+(4x−11)=180∘
⇒3x+2x−7+4x−11=180∘
⇒9x−18=180∘
⇒9x=(180+18)∘
⇒9x=198∘
⇒x=1989∘
∴x=22∘
