Question

⑦ In figure, . Find the value of a, b, c and d.​

Answer 1

Answer:

a= 120,b=60,c=60,d=120.

Step-by-step explanation:

∠a= 180°- 60°= 120° (Adjecent Angles)

∠b= 180°-∠a, 180°-120°=60° (Supplementary Angles)

∠c=∠b=60° (Vertically Opposite Angles)

∠d=∠a=120° (Alternate Angles)

Answer 2

Answer:

d=120

b=c=60

a=120

Step-by-step explanation:

first find the value of d by the concept of linear pair, opp angles of parallelogram and vertically opp. angle then find the value of b by the concept of linear pair , then find the value of c, b and c are vertically opp. angles so they are equal. then find the value of a by the concept of sum of adjacent angles is 180 degree .
