Blababa [14]3 years ago
7 0

Answer:

angle 1, 5, 7

Step-by-step explanation:

angle 3 = angle 1 (vertically opp angles)

angle 3 = angle 5 (alt angles, parallel lines)

angle 3 = angle 7 (corresponding angles, parallel lines)

Topic: angle properties

If you like to venture further, feel free to check out my insta (learntionary). It would be best if you could give it a follow. I'll be constantly posting math tips and notes! Thanks!

atroni [7]

Answer:1752

Step-by-step explanation: So what you need to do is to multiply the number of copies that the small copier makes with the 4 because it says that it makes it 4 times what the smaller copier does.

Simplify the expression.<br> (the quantity x to the one-sixth power end quantity to the power of 3.)
Usimov [2.4K]

Answer:

\sqrt{x}

Step-by-step explanation:

If we have that worded expression, we can convert it into actual mathematical terms.

x to the one sixth power: x^{\frac{1}{6}}

That to the power of 3:

(x^{\frac{1}{6}})^3

Using exponent rules, since we have a power to a power, the powers multiply, so:

x^{\frac{1}{6}\cdot 3}\\\\x^{\frac{3}{6}}\\\\ x^{\frac{1}{2}}

If we have a number to a fraction power, the denominator becomes the “find the (denominator) root of x.

So:

x^{\frac{1}{2}} = \sqrt{x}

Hope this helped!

In right trapezoid MNPQ
Gala2k [10]

Answer:

  about 252.78 ft

Step-by-step explanation:

Define angle QMP as α. Then ...

  MN = 60·sin(α)

  NP = 60·cos(α)

  area MPN = (1/2)(MN)(NP) = 1800sin(α)cos(α)

__

  PQ = 60tan(α)

  area MPQ = (1/2)(MP)(PQ) = 1800tan(α)

__

The ratio of areas is 2.5, so we have ...

  1800tan(α) = 2.5·1800sin(α)cos(α)

  1 = 2.5cos(α)² . . . . . . divide by 1800tan(α)

  cos(α) = √0.4 . . . . . . solve for cos(α)

__

Then the perimeter is ...

  Perimeter = MN +NP +PQ +QM = 60sin(α) +60cos(α) +60tan(α) +60/cos(α)

  = 60(sin(α) +cos(α) +tan(α) +sec(α))

  = 60(0.774597 +0.632456 +1.224745 +1.581139)

  = 60(4.212936) = 252.776

The perimeter of the trapezoid is about 252.776 feet.

_____

With perhaps a little more trouble, you can find the exact value to be ...

  perimeter = (6√10)(7+√6+√15)
