7. 2x+6x+8 = 32
8x+8=32
-8 -8
8x=24
— —
8 8
X=3
5. 34 because 4 and 2 are the same angle

3. 2x+24=146 is x=61

4.symetric property

6. 4 is 110 since it is equal to two and 1 is 70 since 180 - 110 is 70 and 3 is equal to 1

1.refective property

2. 2y/5

Answer:

solution,

Let <DEF= x°

<CDE= 2x°

<BAF= 90°

The sum of interior angle of hexagon= 720°

<A + <B + <C + <D + <E +<F = 720°

$90 + 145 + 115 + 2x + x + 160 = 720 \\ 510 + 3x = 720 \\3x + 510 = 720 \\ 3x + 510 - 510 = 720 - 510 \\ 3x = 210 \\ \frac{3x}{x} = \frac{210}{3} \\ x = 70 \: degree$

Again,

$< \: cde = 2x \\ \: \: \: \: \: \: \: \: \: \: \: \: = 2 \times 70 \\ \: \: \: \: \: \: \: \: \: \: \: \: = 140 \: degree$

Hope this helps...

Good luck on your assignment..

You want to make a rectangular banner that is 18ft. Long with a trim around the entire border of the banner . You have no more t

lys-0071 [83]

Answer:

6 ft

Step-by-step explanation:

Given that:

Length of rectangular banner = 18 ft

Total trim of banner available = 48 ft

To find:

Possible widths of the banner = ?

Solution:

Maximum trim available of the banner around the entire border of the banner = 48 ft

i.e. we are given the total perimeter of the rectangular banner.

Formula for perimeter of a rectangle is given as:

$Perimeter = 2 \times (Length + Width)$

Putting the values of perimeter and length to find the value of width.

$48 = 2 \times (18 + Width)\\\Rightarrow 48 =36+2 \times Width\\\Rightarrow 2 \times Width = 48-36\\\Rightarrow 2 \times Width = 12\\\Rightarrow \bold{Width = 6\ ft}$

So, width possible is <em>6ft.</em>

HELP PLEASE PLEASE HELP<br> Solve for t.<br> -10t − -17t − 10t + -13 = 11

Marta_Voda [28]

-10t - (-17t) - 10t + (-13) = 11 (two negative signs makes a positive)

-10t + 17t - 10t - 13 = 11 Combine like terms

-3t - 13 = 11 Add 13 on both sides

-3t = 24 Divide -3 on both sides

t = -8
