Jimmy went to the toy store. He saw 23 wooden trains and 41 plastic trains.how many more plastic trains than wooden trains did he see?

Answer:

Your value of x will be 28°

Step-by-step explanation:

First, we'll need to find the length of the two obtuse angles. To do this, you add them together. 124 + 124 = 248°.

Since we know that the entire interior measure of the figure is 360°, you have to subtract 248 from 360 to find out the measure of the two unknown angles together.

The sum of the two unknown angles is 112°.

Now, you have to divide 112 by 4, since both of the angles multiply x by two.

112 divided by 4 is equal to 28.

This means the value of x is equal to 28°

I'll check this just to be sure. First I'll start with the top two angles:

2 x 28 = 56

56 + 56 = 112

Then I'll add it to the bottom two angles:

248 + 112 = 360°

I hope this answers your question!

Hi Brainiac

y= 5x-9

y= 2x+6

We need to solve y=5x-9 for y

Let's start by substitute 5x-9 for y in y=2x+6

y=2x+6

5x-9=2x+6

Add -2x to both sides

5x-9-2x=2x+6-2x

3x-9=6

Now add 9

3x-9+9= 6+9

3x=15

Now divide both sides by 3 so we find the value for x

3x/3= 15/3

x= 5

Now we have x :)

We gonna find the value for y by substitute  5 for x in y=5x-9

y=5x-9

y= 5(5)-9

y=25-9

y= 16

Final answer : x= 5 and y=16

It was my pleasured to help you :0 Good night.

Answer:

0

Step-by-step explanation:

Using the algebraic expansion

x³ + y³ = (x + y)³ - 3xy(x + y)

Given

x³ + y³ - 12xy + 64

= (x + y)³ - 3xy(x + y) - 12xy + 64

Substitute x + y = - 4 into the expression

= (- 4)³ - 3xy(- 4) - 12xy + 64

= - 64 + 12xy - 12xy + 64

= 0

Answer:

1 = 35

2 = 55

Step-by-step explanation:

so we know that between 1 and 2 it is 90 degrees we also know that angle 1 and the angel to the left of it make 180 degrees so do

180 - 90 = 90

this means the angle next to line 1 is also 90 degrees

then we would see that the 55 degrees the 90 degrees and angle 1 make 180 degrees so do

55 + 90 = 145

180 - 145 = 35 degrees so angle 1 is 35 degrees

then we would find angle 2

90 - 35 = 55 degrees so angle 2 = 55

hope this helps : )

Answer:

see explanation

Step-by-step explanation:

(6)

55° and ∠2 are vertical angles and congruent, hence

∠2 = 55°

∠1 and ∠2 are complementary angles ( They form a right angle )

∠1 = 90° - 55° = 35°

(7)

132° and ∠2 are alternate angles and congruent, hence

∠2 = 132°

∠1 and ∠2 are supplementary ( straight angle )

∠1 = 180° - 132° = 48°
