Solve for the values of x and y in each item to make the given quadrillater a parallelogram​
maria [59]

Answer:

For given parallelogram, the value of x = 114° and y = 66°

Step-by-step explanation:

(Refer figure)

Given quadrilateral ABCD is a parallelogram.

m∠A = 66°

m∠B = x°

m∠C = y°

m∠D = 114°

Since by properties of parallelogram, the both pairs of opposite sides of a parallelogram are parallel.

Opposite angles of a parallelogram are congruent ...........................(1)

Consecutive angles of a parallelogram are supplementary ................(2)

Using (1) for given parallelogram ABCD; we get,

m∠B = m∠D

m∠A = m∠C

Therefore x = 114° and y = 66°.

Using (2) to check whether the two consecutive angles are supplementary.

( m∠A + m∠D ) =  ( m∠B + m∠C ) = ( m∠C + m∠D ) = 66° + 114° = 180°

Hope it helps!!

2x^2+9x=-7 <br> Solve round to nearest tenth
Drupady [299]

Answer:

  x = -3.5 or -1

Step-by-step explanation:

Add 7 and factor.

  2x^2 +9x +7 = 0

  (2x +7)(x +1) = 0

  x = -3.5   or   x = -1 . . . . . values that make the factors zero

<em>Comment on factoring</em>

Factoring ax^2 +bx +c = 0 requires you find factors of ac that have a sum of b. Here, you're looking for factors of 2·7 = 14 that have a sum of 9. If you're observant, you realize that 2+7=9, so 2 and 7 are the factors you want.

Now, you can write the factored form as ...

  (ax +p)(ax +q)/a = 0 . . . . where p and q are the factors of ac we just found

The divisor "a" is used to simplify one or both of the factors. Here, we have ...

  (2x +2)(2x +7)/2 = 0

  (x +1)(2x +7) = 0 . . . . . . we removed a factor of 2 from the first binomial

A knitted hat pattern comes in 4 styles with 4 stitch options and 3 sizes, and there are 7 yarns appropriate for the hat. Disreg
Rzqust [24]
In order to find the number of hats, multiply all the choices together, disregarding size:

4 * 4 * 7 <-- 4 styles * 4 stitches * 7 yarns
= 16 * 7 = 112 

112 different hats can be made.
