Given JKMN is a square and NM= 4x and KM = 6x - 16, find all missing angle measures and side lengths.

kirza4 [7]

Answer:

The side lengths are 32 units each

Step-by-step explanation:

Given

$NM= 4x$

$KM = 6x - 16$

Required

The side lengths and missing angles

Since JKMN is as square, then:

$NM = KM$ -- all sides are equal

$4x = 6x - 16$

Collect like terms

$4x - 6x = - 16$

$-2 x = - 16$

Divide by -2

$x = 8$

Substitute $x = 8$ in $NM= 4x$

$NM = 4 * 8$

$NM = 32$

The missing angles can't be solved without an attachment.

<em>However, if the missing angles are the angles at the edges of the square, then they measure 90 degrees each (i.e. angles at right angle)</em>

There are four blue marbles, an unknown number of red (r) marbles, and six yellow marbles in a bag. Which expression represents

MAXImum [283]

Answer:

There are a total of 4 + r + 6 marbles in the bag

The probability of a blue is $\frac{4}{10+r}$

The probability of a red is $\frac{r}{10+r}$

The probability of choosing a blue, replacing it and then a red is

$\frac{4}{10+r}$ × $\frac{r}{10+r}$ = [tex]\frac{4r}{100+20r+ r^{2} /[tex]
