Which equation is correct?

triangle ACB, angle C is a right angle, angle B measures g degrees, angle A measures h degrees, segment AC measures x, segment CB measures y, and segment AB measures z

sin g° = z ÷ x
sin g° = x ÷ z
tan g° = z ÷ x
tan g° = x ÷ z

sin g° = x ÷ z

Step-by-step explanation:

Given a right angled triangle with the following dimension

Triangle ACB, angle C is a right angle, angle B measures g degrees, angle A measures h degrees, segment AC measures x, segment CB measures y, and segment AB measures z.

Find the diagram in the attachment.

Using the SOH, CAH, TOA identity

When considering angle g°, the opposite side of the triangle will be the side facing the angle g° i.e x

Hypotenuse is the longest side |AB| = z

according to SOH,

Sin g° = Opposite/Hypotenuse

Sin g° = |AC|/|AB|

Sin g° = x/z

Therefore sin g° = x ÷ z is correct

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.
