1st angle of triangle =>90°
Let 2nd angle =>1×x=1x or x
Let 3rd angle => 2x
As we know that sum of all the angles of the triangle is equal to 180°
Therefore,
90 + x + 2x = 180°
3x = 180-90
3x = 90
x = 90/3
x = 30
=> 1st angle=>90°
2nd angle =>x = 30°
3rd angle => 2x = 2× 30° =60°
Let 2nd angle =>1×x=1x or x
Let 3rd angle => 2x
As we know that sum of all the angles of the triangle is equal to 180°
Therefore,
90 + x + 2x = 180°
3x = 180-90
3x = 90
x = 90/3
x = 30
=> 1st angle=>90°
2nd angle =>x = 30°
3rd angle => 2x = 2× 30° =60°
