Answer 1

Answer:

...................................

Answer 2

Answer:

65,115,65 and 115.Check below for explanation :D

Step-by-step explanation:

Let angle B and angle D be x.

Given:

(A+C)=130

To find: measure of each angle

Soln: We know that,

sum of all angles of parallelogram = 360 degree

and,opposite angles of parallelogram are equal

Therefore.

A + B + C + D=360 degree

130 + B + D = 360

x + x =360 - 130

2x=230

x= 230/2

x = 115

Therefore ,

A=130/2

  =65

B = 230/2

 = 115

C = 130/2

   = 65

D = 230/2

   = 115
