One angle of a triangle is 2/3 x grades and another is 3/2 x degrees while the third is pix/75 radians . express all in degrees

2/3x grades to degrees
2/3x/100×90=3/5x(degrees)

pix/75 radians to degrees
(xπ/75)×90/(π/2)=3/5x(degrees)

another is 3/2 x degrees

express all in degrees
3/2 x +3/5x+3/5x=180
27/10x=180
x=200/3

angle of 2/3 x grades and angle of pix/75 radians
3/5×200/3=40（degrees）

angle of 3/2 x degrees
200/3×3/2=100（degrees）

The correct answer is .44
