Find the length of the side of rhoumbus whose diagonals are of length 6cm and 8cm.​
Artist 52 [7]

Answer:

In a rhombus, the diagonals bisect at right angles. That means half the diagonals form a right angle triangle then we can try the Pythagorean theorem. so -

one side of triangle =  6/2 =3 (half of the diagonal)

other side = 8/2 = 4

a^2 + b^2 = c2

3 ^2 + 4^2 = c^2

9+16 = c^2

c^2=25

c = \sqrt{25} = 5

the hypothenus forms one side of the rhombus and here the hypothenus is 5, so the lenght of a side is 5 !

From the set {80, 19, 11}, use substitution to determine which value of x makes the equation true. 8x = 88 A. none of these B. 1
mel-nik [20]

Answer:

  C.  11

Step-by-step explanation:

Substituting, we have ...

  8{80, 19, 11} ?= 88

  {640, 152, 88} ?= 88

The value from the set that makes the equation true is x = 11.

_____

<em>Alternate methods of solution (other than substitution)</em>

It can be easier to make use of your knowledge of factoring:

  8x = 8·11

  x = 11

Or to make use of your knowledge of numbers (place value):

  8·10 = 80

so x will not be very different from 10.
