a. ∠C + ∠M is an acute angle.

b. ∠C is an obtuse angle.

c. The supplementary angle to ∠C has the measure of 125°

d. The equation 11 + 27 = 90 is a true statement for the value of .

e. ∠M and ∠C complementary.

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.
