If sin(x) = 1/3 and sec(y) = 29/21, where x and y lie between 0 and /2, evaluate the expression. cos(x − y)

x=0.3398369 and y=0.76101275

cos(x-y)=0.91260884...

Step-by-step explanation:

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
