Let the angles of triangle be angle a,b,c
Angle a = Angle b = x
Angle c = x - 15
Therefore,
angle (a + b + c) = 180 (angle sum property)
= x + x + (x - 15) = 180
= 3x - 15 = 180
= 3x = 195
= x = 195/3
= x = 63
Angle a = Angle b = x
Angle c = x - 15
Therefore,
angle (a + b + c) = 180 (angle sum property)
= x + x + (x - 15) = 180
= 3x - 15 = 180
= 3x = 195
= x = 195/3
= x = 63
