Find the missing angle measure

35

Step-by-step explanation:

let the missing angle be x

x+95+50=180( angle sum property of a triangle)

x+145=180

x=180-145

x=35

therefore, the missing angle is 35

78.59 is the mean

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.
