Sum of the digits of a two digit number is 9. when we interchange the digits the new number is 27 greater than the earlier number. find the number

36

Step-by-step explanation:

Because the sum of 2 number is 9 so we have all posible number with sum is 9:

18, 27, 36, 45, 54, 63, 72, 81, 90

When we intercharge it, it become 27 greater than the original number, so that number would be:

18 => 81 (63 greater) wrong

27 => 72 (45 greater) wrong

36 => 63 (27 greater) right

So 36 would be the number that you are looking for!

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
