3. In the fig. AD = DC and AB = BC. Prove that ΔADB = ΔCDB<br>​
xxMikexx [17]

Answer:

The two column proof is presented as follows;

The given parameters are;

\overline {AD} = \overline {DC} and \overline {AB} = \overline {BC}

Statement               {}                     Reason

\overline {AD} = \overline {DC} and \overline {AB} = \overline {BC}       {}       Given

\overline {BD}  ≅  \overline {BD}               {}                    Reflexive property

\overline {BD}  =  \overline {BD}               {}                     By the definition of congruency

ΔADB ≅ ΔCDB             {}                By Side-Side-Side (SSS) rule of congruency

ΔADB = ΔCDB              {}                 By the definition of congruency

If the three sides of one triangle are congruent to the corresponding three sides of another triangle, then both triangles are said to be congruent according to the SSS rule of congruency

Using geometry, calculate the volume of the solid under z=64−x2−y2and over the circular disk x2+y2≤64
Anarel [89]
Perhaps you mean to find the volume under z=\sqrt{64-x^2-y^2}? It seems like you have to rely on calculus otherwise (in the case that you indeed mean z=64-x^2-y^2).

Assuming this, note that z=\sqrt{64-x^2-y^2} describes the top half of a sphere with radius 8, which means the volume below this surface over the disk x^2+y^2\le64 is simply half the volume of the sphere. Thus the volume is

\dfrac43\pi8^3=\dfrac{2048}3\pi

Please help me AAAAAA
bezimeni [28]

Answer:

45

Step-by-step explanation:

AEF is a similar triangle to ABC. that means it has the same angles, and the sides (and all other lines in the triangle) are scaled from the ABC length to the AEF length by the same factor f.

now, what is f ?

we know this from the relation of AC to FA.

FA = 12 mm

AC = 12 + 28 = 40 mm

so, going from AC to FA we multiply AC by f so that

AC × f = FA

40 × f = 12

f = 12/40 = 3/10

all other sides, heights, ... if ABC translate to their smaller counterparts in AEF by that multiplication with f (= 3/10).

the area of a triangle is

baseline × height / 2

aABC = 500

and because of the similarity we don't need to calculate the side and height in absolute numbers. we can use the relative sizes by referring to the original dimensions and the scaling factor f.

baseline small = baseline large × f

height small = height large × f

we know that

baseline large × height large / 2 = 500

baseline large × height large = 1000

aAEF = baseline small × height small / 2 =

= baseline large × f × height large × f / 2 =

= baseline large × height large × f² / 2 =

= 1000 × f² / 2 = 500 × f² = 500 ×(3/10)² =

= 500 × 9/100 = 5 × 9 = 45 mm²
