Which number produces a rational number when added to 0.25?

Rational numbers are those numbers that can be written as a fraction in form a/b where b ≠ 0.

So, 0.25 = 25/100 and simplify into 1/4.

Any rational number added to 0.25 gives a rational number.

For example: 1, 0.5, 0.75, 2.25 etc.

0.75 can be added to 0.25 to make it 1 i.e a rational number; and many more numbers can also be added

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !
