Question

in a right angled triangle, one acute angle is 30 degrees, find the other acute angle

Answer 1

60° is another angle
180°=90°+30°+x°{Angle sum property}
180°=120°+x°
x°=60°

Answer 2

Right angle =90 degree
Other angle = 30 degree
Third angle= x
Sum of all angles of a triangle is 180 degree
90+30+x=180
120+x=180
X=180-120
X=60
Other acute angle is 60
