we can WRITE it as a+11d=47-a EQ (where a is FIRST term and d is COMMON difference

similarily

we can write 18th term as a+17d=71-b eq

subtract a eq from b eq

we get d=4

a=3

40th term=a+(40-1)d

therefore 3+(39)4=3+156=159

The sum of the interior angles of a polygon is 10 right angles then the number of sides is

Answer»

Answer:

7 = no. of sides of the polygon

Step-by-step EXPLANATION:

Sum of INTERIOR angles = 10*90 = 900
