Question

If one angle of a parallelogram is 60 degrees, find the number of degrees in the remaining three angles.

Answer 1

Wegnerkolmp2741o is wrong.

Explanation:

of one side of the paralleogram is 60 then so is another side

a

b=60

c=60

d=

2a+120=360

-120 -120

240

divide 240 by 2 and angles a and are 120

one way to check this is to multiply 120 by 3 and you get 360

Answer 2

The remaining 3 angles are 300 degrees

Explanation:

The sum of the interior angles of a parallelogram is 360 degrees

We know one angle is 60

360 -60 = 300

The remaining 3 angles are 300 degrees
