Question

Question 10. If two adjacent
angles of a parallelogram are
(5x-5)°and (10x+35)° then the
ratio of these angles is *​

Answer 1

Answer:

1:3

Step-by-step explanation:

sum of adjacent angles if parallelogram=180

5x-5+10x+35=180

15x=150

x=10

therefore angles are 45 and 135

hence its ratio is 1:3
