Question

If one angle of parallelogram is 105 degree .Find the other angles and ratio between the 4 angles

Answer 1

        Opposite angles of a parallelogram are Equal.

Sum of angles of quadrilateral is 360.

If other two sides are x,

105 + 105 + x + x = 360

210 + 2x = 360

2x = 150

x =  75

Ratio = 105:75

          =6/5

Answer 2

Answer:

Step-by-step explanation:

Opposite angles of a parallelogram are Equal.

Sum of angles of quadrilateral is 360.

If other two sides are x,

105 + 105 + x + x = 360

210 + 2x = 360

2x = 150

x =  75
