15. One of the angles of a linear pair is 72°. The other angle is *

16. In the adjoining figure, AB || CD. If ∠APQ = 130°, then ∠PQD

17. Vertically opposite angles have *

18. The difference between the sums of two supplementary angles and two complementary angles is *

19. In the adjacent figure , the value of x is *

20. The value of (3/2)^3 ÷ (3/8)^3 is​​

Answer 1

Answer:

15. linear pair = 72°

so, x= 72°+ 180°=252°

16. angle APQ=130°

angle PQD = X

x= 130+180

=310°
