If the area of AABC is D, give the expressions that complete the equation for the measure of ZB? m m=
n =

Given:

The figure of triangle ABC.

The area of the triangle ABC is D.

To find:

The value of m and n in the given expression.

Solution:

Let h be the height of the triangle ABC.

Area of a triangle is:

Where, b is the base and h is the height of the triangle.

The area of the triangle ABC is D.

                 ...(i)

In a right angle triangle,

             [Using (i)]

           ...(ii)

We have,

         ...(iii)

On comparing (ii) and (iii), we get

Therefore, the required values are .

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.
