149x-330y=-511 --------eq 1 -330x+149y=-32 --------eq 2 Subtract eq 2 from eq 1, we get, 479x-479y=-479 By removing common we get, x-y=-1 ---------eq 3 Add eq 2 in eq 1 we get, -181x-181y=-543 By removing common we get, x+y=3---------eq 4 By elimination method, Subtract eq 4 from eq 3 we get, x=2 By putting the value of x in eq 4 we get, y=1 So the value of x= 2and y= 1

Then √2=a/b (where a and b are co-prime) Then b√2=a ---1 Then (b√2)^2=a^2 Then b^2*2=a^2 Then 2bsquare equal to a square

8/15 will be value of tan
Thanks for answer

Vinod Vyavhare 2 years ago

cosec a = 17/8 which is hypo/perpendicular. So by Pythagoras there we get the base as 15 then tan a = perpendicular/base so it is 8/15

a=11 D=8-11= -3 an = -150 an=a + (n-1)d -150 = 11+ (n-1)-3 -150= 11-3n+3 -150 = 14 -3n -150 -14 = -3n -164 = -3n n = -164/-3 n =54.6... So ,-150 is not a term of the given AP. ........Harika

Nayan Gaur 2 years ago

-52=n So,-150 is not a term of A.P.

Xn = a +(n-1)d

-150=11+(n-1)×-3

-150-11=(n-1)×-3

-161=   (n-1)×-3

-161÷-3=(n-1)

-53.6=(n-1)

​​​​​​​n=54.6,it is not positive intiger, so -150 is not a term if these sequence

3x+4y=10----(1) 2x-2y=2------(2) Now multiplying by 2 in equation (2) 3x+4y=10------(3) 4x-4y=4--------(4) Solve equation 3 and 4 7x=14 X=2 Now putting the value of x in equation 1 3(2)+4y=10 6+4y=10 -4y=10-6 -4y=4 Y= 1

Arjun Sharma 2 years ago

3x + 4y = 10 -----(1) 2x-2y = 2 --------(2) Multiply (2) equation with 2 4x - 4y = 4 -------(3) Add 3 and 1 3x + 4y = 10 4x - 4y = 4 ----------------------- 7x = 14 X = 2 Similarly Y=1
