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

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
