The total surface area is _ square centimeters

algol13

Answer:

180 square inches

Step-by-step explanation:

First off since the square will be easiest to do

a=a^2

a=6^2

a=36

now for the triangles

a= height of triangle * base/ 2

a= 12*6/2

a= 36

and since there is 4 of the triangles we multiply 36 by 4

=144

now we add 144 to 36 and we have the total

A 30-meter high building sits on top of a hill. The angles of elevation of the top and bottom of the building from the same spot

Vladimir79 [104]

<h2>A 30-meter high building sits on top of a 151.52 meter high hill.</h2>

Explanation:

According to the given data, we can draw a figure (Please refer the attachment below)

Building's height = 30 meter

Angle of elevation from a spot to the top of the building = 55 degrees

Angle of elevation from the spot to the top of the building = 50 degrees

To find the height of the hill, we need to use the formula,

$tan \,\theta = \frac{opposite \,side}{adjacent \,side}$

then, $tan \,50 = \frac{h}{x}$

$\Rightarrow x = \frac{h}{tan 50}$

$\Rightarrow x = \frac{h}{1.192}$ .... (1)

Similarly, $tan \,55 = \frac{30+h}{x}$

$\Rightarrow x = \frac{30+h}{tan 55}$

$\Rightarrow x = \frac{30+h}{1.192}$ .... (2)

(1) = (2) becomes

$\frac{h}{1.192} = \frac{30+h}{1.428}$

[tex]\Rightarrow [tex] 1.428h = (30 + h)1.192

1.428h = 35.76 + 1.192h

1.428h - 1.192h = 35.76

0.236h = 35.76

h = 151.52 meter

Therefore, the hill highs 151.52 meter.
