The difference between the supplementary angle and the complementary angle of any acute angle is............. (in $^{\circ}$)

If an angle is $20^{\circ}$ more than its complementary angle,then the measure of that angle is $\ldots \ldots \ldots$ (in $^{\circ}$)

In the given figure,if $AB \parallel CD$,$\angle PCD = 130^{\circ}$ and $\angle PBA = 140^{\circ}$,then find $\angle BPC$. (in $^{\circ}$)

Find the measure of an angle,which is one-eighth of the measure of its supplementary angle. (in $^o$)

If the measure of an acute angle is $x^{\circ}$,find the difference of the measure of its supplementary angle and complementary angle. (in $^{\circ}$)

In the figure,$DE \parallel QR$ and $AP$ and $BP$ are bisectors of $\angle EAB$ and $\angle RBA$ respectively. Find $\angle APB.$ (in $^{\circ}$)
