4x=180
X=45.
So;third angle will be 2×45=90
Hope it helps.

let angle of 1 side be x
angle of 2 side be y
and third side be z
Given- x+y= z
sum of all angles of a triangle =180°
x+y+z = 180
we can also write z as x+y as stated above
Now,
x+y+x+y= 180°
=> 2x+2y=180°
=>2(x+y)=180°
=>x+y=90°
So, z=90°. (x+y)
angle of 2 side be y
and third side be z
Given- x+y= z
sum of all angles of a triangle =180°
x+y+z = 180
we can also write z as x+y as stated above
Now,
x+y+x+y= 180°
=> 2x+2y=180°
=>2(x+y)=180°
=>x+y=90°
So, z=90°. (x+y)
