Temperature sensor produces an output
Vs= (43.2mv)T'C + 750mv
This express in term of temperature versus sensor voltage (vs)
T=(vs-0.75)/0.0432'C

To design using combination of inverting, non inverting and summing amplifier togather with 1V reference voltage source .
The sensor voltage Vs and 1v ref source Vref are two input signal of the circuit.Design circuit should produce an output voltage Vo to indicate the temperatureaccording to equation Vo= T/10.('C/10)
When T=0'C , Vo =0v
T=100'C , Vo = 10v .

Base on this can we get the resistor value for the amplifier using?

What resistor value? You need to first get a circuit topology that you think will work. There's no point talking about unspecified resistors in unspecified circuits.
