Find the measure of the missing angle.
98°
a

a = 82

Step-by-step explanation:

Both angles form to create a supplementary angle. A supplementary angle is when two angles add up to be 180 degrees. We can write an equation and solve.

98 + a = 180

a = 82

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.

step-by-step explanation:

mean or average is 40.6
