How can you tell that c || d, if it’s given that a || b and 2 is congruent to 12

Can't wait to learn geometry (shapes math) in a year or 1/2. This looks very interesting and mind blowing.

Step-by-step explanation:

d

step-by-step explanation:

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.
