Question

ABCD is a parallelogram in which angle A=110° .Find the measure of each of the angle B angle c and angle D​

Answer 1

Answer:

Given ∠A = 110o But we know that sum of adjacent angles of a parallelogram is 180o ∠A + ∠B = 180o 110o+ ∠B = 180o ∠B = 180o– 110o= 70o. Also ∠B + ∠C = 180o [Since ∠B and ∠C are adjacent angles] 70o+ ∠C = 180o ∠C = 180o– 70o= 110o. Now ∠C + ∠D = 180o [Since ∠C and ∠D are adjacent angles] 110o+ ∠D = 180o ∠D = 180o– 110o= 70oRead more on Sarthaks.com - https://www.sarthaks.com/738545/abcd-is-a-parallelogram-in-which-a-110-find-the-measure-of-each-of-the-angles-b-c-and-d

Answer 2

Answer:

Step-by-step explanation:

b=180-110=70[adjacent angles]

d=b=70 [ vertically opposite angles ]

c=a=110 [ vertically opposite angles ]
