You may someday purchase a house that has 2500 square feet of living space. how many square meters of living space is this?

Korolek [52]

It is given in the question that,

You may someday purchase a house that has 2500 square feet of living space.

And we need to convert square feet to square meters .

$1 meter= 3.28 feet$

Therefore,

$1 feet = \frac{1}{3.28} meter$

Squaring both sides

$1 ft^2 = \frac{1}{10.7584}m^2$

Therefore,

$2500 ft^2 = \frac{2500}{10.7584} m^2
\\
2500 ft^2 = 232.4m^2$

A common design for a mountain cabin is an A-frame

Kipish [7]

Answer:

54.98 degrees.

Step-by-step explanation:

In the diagram, the sides of the A-Frame are lengths AB and BC. The width of the cabin is length BC. We are to determine the measure of the angle at B, i.e. the angle between the two sides of the roof.

Using Cosine Rule:

$b^2=a^2+c^2-2acCos B\\Cos B=\dfrac{b^2-a^2-c^2}{-2ac} \\B=arcCos(\dfrac{b^2-a^2-c^2}{-2ac} )\\a=26, b=24, c=26\\B=arcCos(\dfrac{24^2-26^2-26^2}{-2*26*26} )\\=arcCos 0.5739\\B=54.98^0$
