Answer:
Sin(17) = 0.29
Cosine (78) = 0.21
Step-by-step explanation:
This problem bothers on the trigonometry.
Here we are presented with two trigonometric numbers
Sine (17) and cosine (78)
1.Let us begin by using our calculator to find Sine (17).
Remember to set your calculator in degrees
Sin(17) =0.2923
To the nearest hundredth we have
Sin(17) = 0.29
2. We can do likewise for cosine(78) setting our calculator in degrees
Cosine (78) = 0.2079
To the nearest hundredth we have
Cosine (78) = 0.21
