Answer

\(\boxed{\sin(75^\circ) = 0.97}\)

Steps

Step 1 :Calculate the values of the trigonometric functions for the given angles:

Step 2 :\(\cos(3^\circ) = 0.9986\)

Step 3 :\(\tan(18^\circ) = 0.3249\)

Step 4 :\(\sin(75^\circ) = 0.9659\)

Step 5 :Compare the calculated values with the provided values:

Step 6 :\(\cos(3^\circ) \neq 0.20\)

Step 7 :\(\tan(18^\circ) \neq 0.93\)

Step 8 :\(\tan(18^\circ) \neq 0.23\)

Step 9 :\(\sin(75^\circ) \approx 0.97\)

Step 10 :\(\boxed{\sin(75^\circ) = 0.97}\)
