In the diagram below, the segments intersect at point M. The measure of PMR is x°. Which equation can be used to determine the value of x?

A. 90+13+x=180

B.90+c=180+13

C. 180-90=x-13

D. 13-90-180 + x

x=12 units bd= 10 units

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.
