Please Help I Have Been On This For Hours :)Find Z(Find The Measure Of The Exterior Angle Of The Polygon)

Answers

Answer 1

Answer:

106

Step-by-step explanation:

If you find the sum of the interior angles, you can determine the supplement to z.

Then all you have to do to get z is to subtract it from 180.

Method

The supplement of 72 is 180 -  72 = 108

The supplement of 51  is 180 - 51 =   129

The supplement of 60 is 180 - 60 = 120

The supplement of 71  is 180 - 71 =   109

Let y = the supplement of z

y + 108 + 129  + 120 + 109 = 540

y + 466 = 540

y = 540 - 466

y = 74

z + y = 180

z + 74 = 180

z = 180 - 74

z = 106

I hope that get's rid of your headache.

Answer:

[tex] \huge \blue{x = \frac{10}{3} } \\ [/tex]

Step-by-step explanation:

[tex] \frac{2}{5} (4x - 3) - 2x = \frac{4}{5} - x \\ [/tex]

Multiply through by 5 to eliminate the fractions

[tex]5 \times \frac{2}{5} (4x - 3) - 2x(5) = 5 \times \frac{4}{5} - 5x \\ 2(4x - 3) - 10x = 4 - 5x \\ 8x - 6 - 10x = 4 - 5x[/tex]

Simplify the terms

[tex] - 2x - 6 = 4 - 5x \\ - 2x + 5x = 6 + 4 \\ 3x = 10[/tex]

Divide both sides by 3

We have the final answer as

[tex]x = \frac{10}{3} \\ [/tex]

A sticker has a length of 4 inches. If Gary places the stickers end to end, how many can he fit on a banner that is 12 feet long? ( 1 foot = 12 inches ) explain why thank you!!!!

A) 144
B) 38
C) 36
D) 42

Answers

Answer:

Step-by-step explanation:

12 feet *12 inches per foot= 144 inches

144/4=36 stickers

C
This is because first you would find out how many stickers are in ONE foot. in one foot there are 3 stickers. Since we know this we then see that the banner is 12 feet long. you would do 3x12 which would end up giving you 36. Hope this helped!

A store sells toys in bulk. It sells wooden blocks for $5 a pound and plastic bricks for $10
a pound. How many pounds of wooden blocks and plastic bricks should be used to make a
A 10-pound mixture that would sell for $80?

Answers

Answer:

six plastic bricks and four wooden blocks

Step-by-step explanation:

plastic bricks=10

wooden blocks:5

lets make plastic x and wooden y

if we made an eight pound mixture of only plastic bricks, that would get us to 80, but would not be enough weight. if we substitute one x pound for two y, we would have 9 pounds and $80. if we substitute this again, we have ten pounds and $80. we added four wooden blocks, and we took two away from the 8 plastic we had, so that is 6 plastic. so we have 6x and 4y, using the variables I assigned for the blocks above.

Answers

Answer: X = -20

Step-by-step explanation:

-12 + x/5 = -16 ( What you do to one side you do to the other )

+12             +12 ( adding 12 to both sides)

x/5 = -4 ( gives us this )

5 (x/5 = -4)    ( I multiplied by 5 to remove the denominator of x )

x =  -20 ( get the answer )

Find the distance from L to AB
AND find the measurement of

Answers

Answer:

[tex]\overline {LD}[/tex] = 0.6 inch

m∠ABC = 60°

Step-by-step explanation:

The given parameters are;

The given triangle ΔABC = A right triangle

The angle bisector of ∠CBA = BL

The length of BL = LB = 1.2 in.

The length of LC = 0.6 in.

We have;

[tex]\overline {LB}[/tex] ≅ [tex]\overline {LB}[/tex] reflexive property

∠ABC = ∠CBL + ∠DBL and ∠CBL ≅ ∠DBL definition of bisected angle

∠CBL = ∠DBL by definition of congruency

∠CLB + ∠CBL = ∠CLB + ∠DBL = 90°, opposite angles of a the right angle triangle are supplementary

∴ ∠CLB = ∠CLB by addition property of equality

ΔLDB ≅ ΔLBC are congruent by the Angle-Side-Angle rule of congruency

∴ [tex]\overline {LD}[/tex] ≅ [tex]\overline {LC}[/tex] Congruent Parts of Congruent Triangles are Congruent (CPCTC)

[tex]\overline {LD}[/tex] = [tex]\overline {LC}[/tex] = 0.6 in. by definition of congruency

[tex]\overline {LD}[/tex] = 0.6 in.

sin(m∠CBL) = Opposite side/(Hypotenuse side) = [tex]\overline {LC}[/tex]/[tex]\overline {LB}[/tex] = 0.6/1.6 = 1/2

m∠CBL = sin⁻¹(1/2) = 30°

m∠CBL = m∠DBL = 30°

m∠ABC = m∠CBL + m∠DBL = 30° + 30° = 60°

m∠ABC = 60°
