Answer:

  the conclusion is not justified. No statement is made regarding the angles of the rhombus

Step-by-step explanation:

A square is a rectangle because of its right angles, not because of its equal-length sides. The rhombus having equal-length sides does not qualify it as a rectangle. The conclusion of the argument is unsupported.

____ [38]
Each football is sold for $9.95. To make one of these football costs $7.10.
There is a profit of $2.85. Divide 11,400 by 2.85 to see how many footballs would have to sell to break even.

11,400 / 2.85 = 4000. 

4000 footballs would have to be sold to break even.

In △ABC, AB = 13, AC = 20, BC = 21. Find the length of the altitude AD
nika2105 [10]

The length of the altitude AD is 12 units.

<h3>How to find the height of a triangle?</h3>

The height of the triangle can be found as follows:

We have to find an angle using cosine law before  we can find the height.

Therefore,

20² = 13² + 21² - 2 × 21 × 13 cos B

400 = 169 + 441  - 546 cos B

400 - 610 = - 546 cos B

-210 = - 546 cos B

cos B = -210 / -546

cos B = 0.38461538461

B = cos⁻¹ 0.38461538461

B = 67.3810899783

B = 67.38°

Hence,

sin 67.38° = opposite / hypotenuse

sin 67.38° = AD / 13

cross multiply

AD = 13 sin 67.38°

AD = 11.9999882145

AD = 12 units
