Use the image below to answer the following question. Find the value of sin x° and cos y°. What relationship do the ratios of sin x° and cos y° share?

They are equal

Step-by-step explanation:

To use the sine/ cosine ratios we require the hypotenuse h

Using Pythagoras' identity

h² = 3² + 4² = 9 + 16 = 25 ← take the square root of both sides )

h = = 5

Thus

sinx° = =

cosy° = =

sinx° and cosy° have equal ratios

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

step-by-step explanation:
