Question

Without actual division, determine which of the following rational numbers have a terminating decimal representation and which have a non-terminating representation. Give Reason. 3/14 ,21/5​

Answer 1

Answer:

Given,

Two angles =650,650

And the other two angles are equal.

Let the other angles be x,x.

Concept used:

The sum of the angles of a quadrilateral is given

=3600

Apply the above concept, we get

650+650+x0+x0=3600

130x0+2x0=3600

2x0=3600−1300

2x0=2300

x0=1150
