(b) 102°, 770, 102°
(c) 105°, 77°, 105°
(d) 103°, 77°, 103°​

Answer 1

77,77'',103,103 please mark me as brainlist answer

Step-by-step explanation:

property of parrallelogram - opposite angles are congruent

so,the angle opposite to77'' is 77''

and now by the property of sum of all angles of a parrallelogram is 360°

77''+77''+x+x=360°

154+2x=360

2x=360-154

2x=206

x=206/2

x=103

property- opposite angles are congruent

angle opposite to 103''is also 103''
