Answer:

zero.

Step-by-step explanation:

To find the value of the expression we need the help of a calculator:

cos 140°= -0,76

sin 10° = 0,17

cos 70° = 0.34

sqrt root (3) = 1.73

Therefore,

cos 140° + sin 10° + sqr root (3) cos 70° = -0,76 + 0,17 + 1.73*0.34 = 0

Therefore the result is zero.
