The height of the fire department is 244.72 m

Step-by-step explanation:

Angle of elevation = 73°

The distance between the two buildings = 46 m

tan 73° = b/46

tan 73° = 3.27

tan 73° = b/46

3.27 = b/46

b = 3.27 x 46

b = 150.42 m

Angel of depression= 64°

The distance between the two buildings = 46 m

tan 64° = a/46

tan 64° = 2.05

tan 64° a/46

2.05 = a/46

a = 2.05 x 46

a = 94.3 m

The total height of the fire department building = a + b

= 94.3 + 150.42

= 244.72 m

The height of the fire department is 244.72 m

HELPP FOR BRAINLEST RIGHT NOW!!!!

Verdich [7]

Answer: Counter, 0, 0.

Step-by-step explanation:

Think about a clock. The hand of a clock goes clockwise. When you tighten something (righty tighty) you spin it clockwise. You can rotate an object, lets say a square, clockwise. You can also rotate it counterclockwise, in the other direction. Therefore, you can rotate an object clockwise and counterclockwise.

You can rotate a figure around any point, such as the center of the figure, the origin, or anywhere else. One common place to rotate a figure around, such as a square, is the origin. This is the center of the coordinate plane. This point is not up, down, left, or right at all from the center. This coordinate is (0, 0). Therefore, the next two blank spaces should both be filled with 0.

The blank spaces should look like this:

One direction is clockwise and the other is counterclockwise.

...

This can be any coordinate point such as the origin which is at ( 0 , 0 )

Slove by using elimination 3x+7y=27 -3x+y=21

tankabanditka [31]

Answer:

x = -5

y = 6

Step-by-step explanation:

3x + 7y = 27 --------------(I)

-3x + y = 21 -----------(II)

Add equation (I) & (II) and so x will be eliminated and we can find the value of y.

(I) 3x + 7y = 27

(II) -3x + y = 21 {add}

8y = 48

y = 48/8

y = 6

Plugin y = 6 in equation (I)

3x +7*6 = 27

3x + 42 = 27

3x = 27 - 42

3x = -15

x = -15/3

x = -5
