Vedclass · Answer

(A) Let the angles of $\Delta PQR$ be $5x$,$2x$,and $2x$ respectively.According to the angle sum property of a triangle,the sum of all interior angles is $180^{\circ}$.Therefore,$5x + 2x + 2x = 180^{\circ}$.$9x = 180^{\circ}$.$x = 20^{\circ}$.Now,calculating each angle:$\angle P = 5x = 5 	imes 20^{\circ} = 100^{\circ}$.$\angle Q = 2x = 2 	imes 20^{\circ} = 40^{\circ}$.$\angle R = 2x = 2 	imes 20^{\circ} = 40^{\circ}$.Thus,the angles are $100^{\circ}, 40^{\circ}, 40^{\circ}$.

In $\Delta PQR$,$\angle P : \angle Q : \angle R = 5 : 2 : 2$. Find the measure of each angle of $\Delta PQR$.
