Question

in the parellelogram ABCD,‹A‹B=4:5.find the measure of each angleof the parellelogram​

Answer 1

Answer:

Step-by-step explanation:

Let the ratio be x. Then,

<A +< B =180 [ sum of adjacent angle ]

4x + 5x = 180

9x = 180

X =20

So, A =4(20) =80

B=5(20) = 100

C = A = 80 [opposite angle of

B = D = 100 parallelogram are

equal ]
