I need help bad. It's about finding angles and I can't really figure it out.

<h3>Answer:  41 degrees</h3>

=========================================================

Explanation:

Angle BFE is 117 degrees. The adjacent angle to this (angle BFA) is 180-117 = 63 degrees since the two angles form a straight line, and must add to 180.

Now because BD is parallel to AE, we know that the alternate interior angles BFA and FBD are the same measure. This makes angle FBD to be 63 degrees.

We're told that segment BF bisects angle ABD. That indicates the two smaller pieces (angles ABF and FBD) are the same measure. Both are 63 degrees in this case.

Let x be the measure of angle DBC. This angle will add to angles ABF and FBD to form a 180 degree straight angle

(angleABF) + (angleFBD) + (angleDBC) = 180

(63) + (63) + (x) = 180

x+126 = 180

x = 180-126

x = 54

Angle DBC is 54 degrees.

-----------------------

The last set of steps has us focus on triangle BCD. The three angles of any triangle always add to 180.

B+C+D = 180

54 + 85 + D = 180

139 + D = 180

D = 180-139

D = 41

Angle CDB is 41 degrees, and so is angle CEA as they are corresponding angles. Corresponding angles are congruent when we have parallel lines like this.

Therefore, angle E is 41 degrees.

The diagram is below showing all of the angles we found.

Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.
yan [13]

Answer:

1. ║u-z║= 5.66

2.║v-w║=6.0

3. ║w-u║=6.08

4.║v-u║=7.81

Step-by-step explanation:

The vectors are given as;

u = <-1, -3>, v = <5,-8>, w = <5, -2>, and z = <3, 1>.

To find the magnitude of the vectors;

1. ║u-z║

<-1 - 3> = <-4  and < -3 - 1> = <-4

║<-4,-4> ║= √{ -4²+-4²} = √32 = 5.66

2.║v-w║

   <5,-8> - <5,-2>

   <5-5> , <-8--2>

   <0,-6>

    ║<0,-6>║= √{0²+ -6²} = √36 = 6

3. ║w-u║

    <5,-2> - <-1,-3>

    <5--1> , <-2--3>

    <6,1>

    ║6,1║= √{6²+1²} = √36+1 = √37 = 6.08

4.║v-u║

   <5,-8> - <-1,-3>

    <5--1> , <-8--3>

    < 6 , -5 >

    ║6,-5║= √{6²+-5²} = √36+25 =√61 = 7.81

If the cost of producing a product that sells for $50 is 120,000 plus $20.00 per piece, then how many products must be sold to b
Vadim26 [7]
Let
x--------->number of products
y1--------> <span>the cost of producing a product
y2------> </span><span>the cost of sell a product
</span><span>
we know that
y1=120,000+20x-------> equation 1
y2=50x------> equation 2

equate equation 1 and equation 2
120,000+20x=50x
50x-20x=120,000
30x=120,000
x=4000

the answer is
4000 pieces</span>
