To work with Sine, Cosine, and Tangent, you first need to know their definitions. |dw:1371774217444:dw| Sin(angle) = \(\Large \frac{\text{opposite}}{\text{hypotenuse}}\) Cos(angle) = \(\Large \frac{\text{adjacent}}{\text{hypotenuse}}\) Tan(angle) = \(\Large \frac{\text{opposite}}{\text{adjacent}}\)

OpenStudy (anonymous):

so i just do opposite over hypotenuse

OpenStudy (anonymous):

Correct. Make sure you're careful about identifying which side is the hypotenuse, which side is opposite from the angle, and which side is adjacent to the angle.

OpenStudy (anonymous):

Do you know which side is the hypotenuse?

OpenStudy (anonymous):

from my triangle it would be the side that is 17.46

OpenStudy (anonymous):

and the opposite is 7

OpenStudy (anonymous):

@SmoothMath

OpenStudy (anonymous):

Correct =) SO what is sine of the angle?

OpenStudy (anonymous):

.40091

OpenStudy (anonymous):

and it will stay the same because 0 is less than 5 so we will not round up

OpenStudy (anonymous):

wont it stay the same? because 0 and 1 are less than 5 so we will not round up

OpenStudy (anonymous):

@SmoothMath

OpenStudy (anonymous):

Your answer should have 2 decimal places. .40091 has 5 decimal places.

OpenStudy (anonymous):

so would it be .40

OpenStudy (anonymous):

Correct.
