The length of the hypotenuse, line segment ac, in right triangle abc is 25 cm. the length of line segment bc is 15 cm. which is the approximate measure of angle acb? 31.0° 36.9° 53.1° 59.0°

53.1°

The correct answer is third option

Step-by-step explanation:

It is given that,he length of the hypotenuse, line segment AC, in right triangle ABC is 25 cm. The length of line segment BC is 15 cm

To find the measure of <ACB

From the given information we get BC is the adjacent side of angle C and hypotenuse = 25 cm

Therefore Cos C = Adjacent side/Hypotenuse

 = 15/25 = .6

C = Cos⁻¹(0.6) = 53.1°

Therefore angle ACB = 53.1°

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.
