The no. of degrees in one acute angle of a right-angled triangle is equal to the no. of grades in the other acute angle of the same triangle. Express both the angles in degrees. Please give the solution.

we Know that, 180 degree = 200 grade therefore 1 grade = 9/10 degree let x degree + x grade =90 degree x degree + 9x/10 degree = 90 degree 19x/10 = 90 degree x = 900/19 so angles are 900/19 degree & 810/19 degree
