Answer:
SinB = 28/53 = 0.5283
CosB = 45/53 = 0.8491
TanB = 28/45 = 0.6222
Step-by-step explanation:
To find the trig values of angles when you know all sides, you have to use SOH CAH TOA.
Sin() = Opposite/Hypotenuse
Cos() = Adjacent/Hypotenuse
Tan() = Opposite/Adjacent
Oposite is the side opposite the angle
Adjacent is the side between the angle and the 90° angle
Please give me a good review :)
