Question

the greatest angle of a parallelogram is 30 more than the twice the smallest angle then the greatest angle of a parallelogram is​

Answer 1

Answer:

Let greatest angle be g and smallest angle be s

g=30+2s.....(1)

In parallelogram opposite angles are equal and sum of all 4 angles is 360

2g + 2s = 360

g + s = 180....(2)

s = 180 - g

put this value of s in (1)

g = 30 + 2(180-g)

g=30+360-2g

3g = 390

g = 390/3 = 130 Ans
