Question

in trapezium pqrs PQ parallel to Rs if Angle p is equals to 150 degrees then angle s is equals to

Answer 1

$\textbf{Concept used:}$

$\text{Two angles of non parallel side of a trapezium are supplementary}$

$\textbf{Given:}$

$\angle{P}=150^{\circ}$

$\text{Using the given concept,}$

$\angle{P}+\angle{S}=180^{\circ}$

$\implies\,150^{\circ}+\angle{S}=180^{\circ}$

$\implies\,\angle{S}=180^{\circ}-150^{\circ}$

$\implies\bf\angle{S}=30^{\circ}$
