I’m the parallelogram above, what is the value of x+y

Help please

248°

Step-by-step explanation:

y = 180°- 56°

  = 124°

x = 124° because opposite angles of a parallelogram are equal

x + y = 124° + 124°

        = 248°

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.
