The length of triangle base is 36. The line which is parallel to the base divides the triangle into two equal area parts. Find a

Soloha48 [4]

Answer:

$18\sqrt{2}$

Step-by-step explanation:

Consider triangle ABC with the base AC=36. Let the line DE be parallel to the line AC. If DE||AC, then triangles ABC and DBE are similar. If k is the scale factor of these triangles, then

$\dfrac{DE}{AC}=\dfrac{BG}{BF}=k.$

Thus,

$DE=k\cdot AC=36k,\\ \\BG=k\cdot BF.$

The area of the triangle ABC is

$A_{ABC}=\dfrac{1}{2}AC\cdot BF=\dfrac{1}{2}\cdot 36\cdot BF=18BF.$

The area of the triangle DBE is

$A_{DBE}=\dfrac{1}{2}DE\cdot BG=\dfrac{1}{2}\cdot 36k\cdot kBF=18k^2BF.$

Since line DE divides triangle ABC in two equal area parts, we have that

$A_{DBE}=\dfrac{1}{2}A_{ABC},\\ \\18k^2BF=\dfrac{1}{2}\cdot 18BF,\\ \\k^2=\dfrac{1}{2},\\ \\k=\dfrac{1}{\sqrt{2}}$

and

$DE=\dfrac{1}{\sqrt{2}}\cdot 36=18\sqrt{2}.$

Can someone help me understand this?

Irina18 [472]

Well if we have two angles, LMT and TMN, that make up LMN, then the sum of LMT and TMN should equal LMN.

144 + 23 = 167 degrees.

Hope this helps!

8.What is the lateral area and the surface area of the cone shown below? Round the answers to the nearest tenth.the figure is no

leonid [27]

Answer:

Part 1) The lateral area is $LA=791.7\ ft^{2}$

Part 2) The surface area is $SA=1,244.1\ ft^{2}$

$LA=791.7\ ft^{2}$ , $SA=1,244.1\ ft^{2}$

Step-by-step explanation:

step 1

Find the lateral area of the cone

we know that

The lateral area of the cone is equal to

$LA=\pi rl$

we have

$r=12\ ft$

$l=21\ ft$

substitute

$LA=(3.1416)(12)(21)=791.7\ ft^{2}$

step 2

Find the surface area of the cone

we know that

The surface area of the cone is equal to

$SA=\pi r^{2}+LA$

we have

$r=12\ ft$

$LA=791.7\ ft^{2}$

substitute

$SA=(3.1416)(12)^{2}+791.7=1,244.1\ ft^{2}$
