`x^@` is _____angle

If x + y = 90, then x is the ____ angle of y.

Supplementary angle of x is _______

In the figure two angles, x and y are called _____angles

Angle subtended by an arc at its centre is ‘x^@’ then, angle subtended by it at any other point on the circle is

If x is an acute angle and sin (x + 28^(@))=cos (3x - 78^(@)) , then x =

The two lines 4x^(2)-24xy+11y^(2)=0 makes with x-axis angles such that difference of their tangents is

From the adjacent figure PQ I\I RS , angle RPQ = 52^@ , angle RPS = 65^@ , angle PSR = x^@ and angle PRQ = 3y^@ + 5 , then the value of x + y is

The angles of a quadrilateral are x^@ , (x-10)^@ , (x+30)^@ and 2x^@ . Find the angles.

Find 'x' if the angle between he lines with direction ratios (x,4,5) and (2,-1,2) is 90^(@)
