Question

in the following figure ABCD and PQRS are parallelogram find the value of b​

Answer 1

Answer:

180-(65+80)=35 degrees

Step-by-step explanation:

angleB=angleD=180-100=80

angle S =65

so b= 180-(65+80)=35

Answer 2

Answer:

d=180°-100°=80° ( adjacent angles are supplementry)

S=Q=65° (opposite angles of parallelogram are equal)

∆sdo = 180°

180°-80°+65°= 180°-145°= 35°

B=35°
