73°

Step-by-step explanation:

Given, Angle A = 17° and Angle B = 90°

As it is a triangle, sum of all the angles are 180°

so,

⇒ Angle A + Angle B + Angle C = 180°

⇒ 17° + 90° + Angle C = 180°

⇒ Angle C = 73°

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.

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
