Question

PQRS is a parallelogram find the values of required angles in figure

Answer 1

Answer:35=z, t=145, y=145

Step-by-step explanation: as pqrs is a parallelogram,

therefore 3x+5=z

but z=2x+15

therefore, 2x+15=3x+5

so, x=10

so, 3[10]+5=z

therefore 35=z

now, t=180-[2x+15] by linear pair

therefore t=145

but t=y [opp. angles of a parallelogram are eq.]

therefore y=145
