The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is twice the

measure of the first angle. The third angle is fourteen more than the second. Find the measures (in degrees) of the three angles.

Which expression is equivalent to 64y^18-1000z^6?

Shalnov [3]

For this case we must find an expression equivalent to: $64y ^ {18}-1000z ^ 6$

Then, we take common factor 8:

$8 (64y ^ {18}-125z ^ 6) =$

By definition of power properties we have to:

$(a ^ n) ^ m = a ^ {n * m}$

So:

$8 ((2y ^ 6) ^ 3- (5z ^ 2) ^ 3)$

Since both terms are perfect cubes, we factor using the cube difference formula:

$(a ^ 3-b ^ 3) = (a-b) (a ^ 2 + 2ab + b ^ 2)$

Where:

$a = 2y ^ 6\\b = 5z ^ 2$

So: $8 (2y ^ 6-5z ^ 2) ((2y ^ 6) ^ 2 + 2 (2y ^ 6) (5z ^ 2) + (5z ^ 2) ^ 2) =\\8 (2y ^ 6-5z ^ 2) (4y ^ {12} + 10y ^ 6z ^ 2 + 25z ^ 4)$

Answer:

$8 (2y ^ 6-5z ^ 2) (4y ^ {12} + 10y ^ 6z ^ 2 + 25z ^ 4)$

Answer:

These are two equilateral triangles and all the sides of an equilateral triangle are equal. The question even says so so that's the answer, all the sides of the equilateral triangles are equal so all the sides equate to each other

For a project in her Geometry class, Chee uses a mirror on the ground to measure the

maria [59]

The geometry technique that Chee uses to find the height of the goalpost is the equal ratio of the corresponding sides of similar triangles.

Correct response:

The eight of the goalpost is approximately <u>16.91 meters</u>.

<h3>Methods used to calculate the height</h3>

The length Chee is using the mirror to measure = The height of her school's football goalpost

The distance of the mirror from the goalpost = 14.35 meters

The distance on the other side of the mirror Chee steps to = 1.4 meters

The distance from her eyes to the ground = 1.65 meters

Required:

How tall is the goalpost.

Solution:

By using similar triangles relationships, we have;

$\dfrac{1.65}{1.4} = \mathbf{\dfrac{Height \ of \ the \ goalpost, h}{14.35} }$

Which gives;

$h = \dfrac{1.65}{1.4} \times 14.35 = 16.9125 \approx \mathbf{ 16.91}$

The height of the goalpost, h ≈ <u>16.91 meters</u>
