Question

two adjacent angles of a parallelogram are (7x - 10) and (8x - 5), then the ratio of these angles is


​

Answer 1

Answer:

7x-10+8x-5=180°

15x-15=180°

15x=180°+15

15x=195°

x=13

Answer 2

Answer:

ans=13

Step-by-step explanation:

7x-10+8x-5=180

7x+8x=180+10+5

7x+8x=190+5

15x=195

x=195/15

x=13
