Answer:Since the integers are closed under addition, . m C n C 1/ is an integer, and hence the last equation shows that x C y is even. Therefore, we Page 3 Appendix C. Answers for Exercises 539 have proven that if x and y are odd integers, then x C y is an even integer. P1 There exists an integer k m D 2k.

10/10 in 1 whole and 1/100 in one whole
Step-by-step explanation:
According to the question, sin (0) is (-)ve
therefore, sin(0)= -15/17
AND , tan(0) = sin(0) / cos(0)
= 15/8
