Step-by-step explanation:

Dividing the shape into two:

The area of the rectangle is

A= 13.5*4.8= 64.8km2

the area of the triangle

A = [( 5.7-4.8) *13.5 ]/ 2= 6.075km2

Therefore the total area is

At = 64.8 + 6.075 = 70.875km2

At certain time of day , a 30 meter high building cast a shadow that is 31 meters long . what is the angle of the elevation of t

Nimfa-mama [501]

Answer:

Option C. 44 degree

Step-by-step explanation:

Let

A-----> the angle of the elevation of the sun

we know that

The tangent of angle A is equal to divide the opposite side angle A by the adjacent side angle A

In this problem

The opposite side is 30 meters

The adjacent side is 31 meters

$tan(A)=\frac{30}{31}$

$A=arctan(\frac{30}{31})=44\°$

Please solve with work much appreciated

mamaluj [8]

Answer:

0.046

Step-by-step explanation:

$\text{BAC} = \dfrac{10N - 7.5H}{6.8 M}$

Data:

N = 4

H = 2

M = 80

Calculation:

$\text{BAC} = \dfrac{10N - 7.5H}{6.8M} = \dfrac{10\times4 - 7.5\times2}{6.8\times80} = \dfrac{40 - 15}{544} = \dfrac{25}{544} = 0.046$
