Question

Find the measure of all angles of a parallelogram whose consecutive angles are in the ratio 1 : 3. * (a)60∘,120∘,60∘,120∘ (b)85∘,95∘,85∘,95∘ (c)50∘,130∘,50∘,130∘ (d)45∘,135∘,45∘,135∘​

Answer 1

Answer:

sum of consecutive angles are 180

given ratio 1:3

1+3=4

180/4 = 45

so the one angle will be 45 and other will be 135

Step-by-step explanation:

so (d) is the correct option
