m∠2 = 68°, m∠3 = 112°, m∠4 = 68°

Step-by-step explanation:

m∠3 = m∠1  ( Vertically opposite angles )

m∠3 = 112°

m∠2 = 180 - m∠1

m∠2 = 180 - 112

m∠2 = 68°

m∠4

Solution 1:

m∠4 = m∠2 (Vertically opposite angles)

m∠4 = 68°

Solution 2:

m∠4 = 180 - m∠1

m∠4 = 180 - 112

m∠4 = 68°

Hope this helps

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.
