Answer 2

Answer:

36. 88/7 m  39. 65,115,65,115

Step-by-step explanation:

36.

circumference =2 *$\pi$*r

                        =2*22/7*4

                        =88/7 m

39.

opposite angles of parallelogram are congruent

x+x=130

2 x=130

x=65

adjacent angles add up to 180

therefore 180 -65 =115

the angles are 65,115,65,115
