The areas of two similar triangles are 16 cm2 and 25 cm2. One of the sides of the first triangles is 2 cm. What is the length of
sleet_krkn [62]

Answer:

The length of the corresponding side is 2.5 cm

Step-by-step explanation:

∵ The 2 Δ are similar

∴ Their sides are proportional

∵ The area of first Δ 16 cm²

∵ The area of second Δ 25 cm²

∵ One side of first Δ 2 cm

∵ From similarity (\frac{S1}{S2})^{2}=\frac{A1}{A2}

∴ (\frac{2}{S2})^{2}=\frac{16}{25}

∴ \frac{2}{S2}=\sqrt{\frac{16}{25}}

∴ \frac{2}{S2}=\frac{4}{5}

∴ S2=\frac{(5)(2)}{4}=2.5 cm

Find the perimeter of quadrilateral ABCD with vertices A=(1,1) B=(4,4) C=(7,1) D=(4,-2). Explain your answer.​
Vanyuwa [196]

we have the coordinates of ABCD

there are 2 ways of doing this one is you find the distance of ab, bc, cd and da and then add the answers together. there is another way but i dont remember it properly so i am just gonna do it this way

distance between 2 point = \sqrt{(x_B-x_A)^2+(y_B-y_A)^2}

AB

d = \sqrt {(4 - 1)^2 + (4 - 1)^2}

d = \sqrt {(3)^2 + (3)^2}

d = \sqrt {9 + 9}

d = \sqrt 18

AB = 4.24

now repeat the same with all

BC= 4.24

CD= 4.24

DA= 4.24

so its a square with all the same sides so perimeter is 4 x 4.24

perimeter is 16.96

hope this helps

In her poems, Alice Walker retrieves and ------- parts
GalinKa [24]

The correct answer is option a) revitalizes . . consign to.

In her poems, Alice Walker retrieves and revitalizes parts of Black culture that some have been all too quick to consign to the past as fossilized artifacts.

The meaning of "revive" is "to strengthen," whereas "retrieve" is "to recuperate or regain."

Furthermore, the phrase "consign to the past" refers to sending something into the past in order to get rid of or get away from it, therefore Option A is the best fit for the statement.

As a result, by removing its ancient, fossilized objects, the poet is attempting to reclaim or reinforce some aspects of black culture.
