Question

one angle of a parallelogram can be found by multiplying the other by two and subracting 30 from the product find each angle of tge parallelogram​

Answer 1

Answer:

x = 2y-30 (i)

2x+2y = 360

x + y = 180 (ii)

substituting (i) into (ii) ,we get

2y-30+y = 180

3y = 210

y = 210/3

y = 70

therefore,

x = 2(70) - 30

x = 110
