The world's tallest unsupported flagpole is a 282ft tall steel pole in surrey, british columbia. the shortest shadow cast by the pole during the year is 137ft long. to the nearest degree, what is the angle of elevation of the sun when casting the flagpole's shortest shadow?

a. 26
b. 29
c. 61
d. 64

The angle of elevation of the sun when casting the flagpole's shortest shadow is .

Option (D) is correct .

Step-by-step explanation:

As given

The world's tallest unsupported flagpole is a 282ft tall steel pole in Surrey, British Columbia.

The shortest shadow cast by the pole during the year is 137ft long.

Now by using the trignometric identity .

As the figure is given below

Perpendicular =  AB = 282 ft

Base = BC = 147 ft

Putting all the values in the trignometric identity .

Therefore the angle of elevation of the sun when casting the flagpole's shortest shadow is .

Option (D) is correct .

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.

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
