Elena thinks length BC is 16.5 units. Lin thinks the length of BC is 17.1 units. Do you agree with either of them? Explain or sh
kirill [66]

Answer:

Option D, I agree with neither Elena nor Lin

Step-by-step explanation:

The remaining part of the question is attached herewith

Solution

As we can see in the image  

ED is perpendicular to AB and BC is perpendicular to AB

Thus, as per the Pythagoras theorem,  

AC^2 = AB^2 + BC^2  

14^2 = 6^2 + BC^2

BC^2 = 196-36 = 160

BC = 12.649 OR 12.65

Hence, option D

I agree with neither Elena nor Lin

Perimeter of the carpet = 21.8 m

Area of the carpet = 29.4 $ m^{2}

<u>Given</u>:

<em>Dimension of the living room:</em>

<em />l = 4.9 $ m\\w = 6 $ m

<em>A. </em><em>Perimeter </em><em>of the carpet = perimeter of a </em><em>rectangle</em>

Perimeter = 2(l + w)

Substitute

Perimeter = 2(4.9 + 6)\\= 21.8 $ m

Perimeter of the carpet = 21.8 m (The digits here are significant)

<em>B. </em><em>Area </em><em>of the carper = </em><em>area </em><em>of a </em><em>rectangle </em>

Area = l \times w

Substitute

Area = 4.9 \times 6\\= 29.4 $ m^{2}

Area of the carpet = 29.4 $ m^{2} (the digits here are significant)

Therefore, considering the rules of significant digits:

Perimeter of the carpet = 21.8 m

Area of the carpet = 29.4 $ m^{2}

2. Sled kites rely on wind pressure to retain the shape of the sail. Each consists of a single square and two triangular pieces.
Slav-nsk [51]

Show that the angles A and B are congruent

Answer:

\angle A =\angle B =90^\circ

Step-by-step explanation:

The diagram of the sled kite is attached below.

The central part of the kite is square.

We know by the property of a square that all its angles are congruent and equal to 90 degrees.

Therefore:

\angle A =\angle B =90^\circ

Angles A and B are congruent.
