Question

two angles of triangle are equal and third angle of triangle is 18 greater than each equal angle what measurement of third angle

Answer 1

let the angle be x
the 2 second anle is x
the third angle is 18+x
x+x+18+x=180
x=54
therfore the third angle is 72

Answer 2

x+x+18+x= 180 ( angle sum property of triangle)
3x+18= 180
3x=180-18=162
x=162÷3=54
18+x=18+54=72
I hope it's correct
