angle B is thrice of angle C so
let the angle C be =x
let the angle B = 3x
let the angle A be = 1/2( x+3x)
then,
x+3x+1/2(x+3x) = 180 ( triangle sum property )
4x+1/2 (x+3x) = 180
4x +1/2x + 3/2x = 180
4x + 4/2x = 180
4x + 2x =180
6x = 180
x = 30
angle C = 30
angle A = 60
angle B = 90
let the angle C be =x
let the angle B = 3x
let the angle A be = 1/2( x+3x)
then,
x+3x+1/2(x+3x) = 180 ( triangle sum property )
4x+1/2 (x+3x) = 180
4x +1/2x + 3/2x = 180
4x + 4/2x = 180
4x + 2x =180
6x = 180
x = 30
angle C = 30
angle A = 60
angle B = 90
