Answer:

Angles are 121° , 59°

[MARK THE ANSWER AS BRAINLIEST]

Step-by-step explanation:

Sum  of two adjacent angles of Parallelogram = 180°

∴ 7x - 5 + 3x + 5 = 180°

⇒ 10x = 180°

⇒ x = 180/10 = 18°

∴ Angles

7x - 5 = 7 (18) - 5 = 121°

3x + 5 = 3 (18) + 5 = 59°

Answer 2

Answer:

angles are 121°,59°

Step-by-step explanation:

7x-5+3x+5=180 (sum of cointerior angle)

10x=180

x=18

7x-5= 7×18-5

= 121

3x+5=3×18+5

=59
