Answer:

360

Step-by-step explanation:

The formula is (n-2)180 -> 6(180) = 1080

1080/8=135

135 is the measure of one interior angle so the exterior has to equal 45 for one side.

45 x 8=360

The answer is 360

Step-by-step explanation:

The value of cost he received in change is,

⇒ 55 cents

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

Colin bought a postcard for 45 cents.

And, he gave the cashier $1.

Since, We know that;

1 dollar = 100 cents

Hence, The value of cost he received in change is,

⇒ 100 cents - 45 cents

⇒ 55 cents

Thus, The value of cost he received in change is,

⇒ 55 cents

Add to eliminate y

Step-by-step explanation:

Add to eliminate y

Answer:

First angle = x

Second angle = x - 32

We know that, complementary angles form => 90°

So,

[tex]x + x - 32= 90 \\ 2x = 90 + 32 \\ 2x = 122 \\ x = \frac{122}{2} \\ x = 61[/tex]

First angle,

=> x = 61°

Second angle

[tex]x - 32 \\ = 61 - 32 \\ = 29[/tex]

Second angle,

16 x 1/8 = 2 oz

Answer:

2 ounces left

Step-by-step explanation:

if anna ate 5/8 of the box, and Bill has eaten 1/4 of the box, then in total they’ve eaten 7/8 if the box (1/4 turns into 2/8 + 5/8)

1/8 of the box is left and 1/8 of 16 is 2. so 2 ounces would be left

Answer:

see explanation

Step-by-step explanation:

step 2 : 4x + 4 - 2x = - 6x + 6 + 14

Simplify both sides by collecting like terms ← what was done

step 3 : 2x + 4 = - 6x + 20

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

step 4 : 8x + 4 = 20

Subtract 4 from both sides ← what was done

8x = 16

1 ± i(1/2)√2

Step-by-step explanation:

Write this quadratic in standard form:  subtract 3 from both sides.  This results in 2x^2 - 4x - 3 = 0.  Let's apply the quadratic formula.  The coefficients of the x terms are 2, -4 and -3, so the discriminant is (-4)^2 - 4(2)(-3), or 16 - 24 = -8.

Following the format of the quadratic formula, we get

     -(-4) ±i2√8       4 ±i2√2        

x = ----------------- = --------------- =  1 ± i(1/2)√2

Answer:

696.8 mm^2

Step-by-step explanation:

Well first lets find the bottom part of the square first.

13*13= 169

Thats the floor

13*5= 65

Thats 1 of the sides

there are 4 sides

65*4= 260

260+169= 429

Now find the triangle

(13*10.3) / 2

You’d get 66.95

66.95 *4 since there are 4 sides

You’d get 267.80

267.8+429= 696.8

Answer:

The given two triangles must be similar by AA similarity Condition . Therefore ,

And the corresponding sides of the similar triangles are Proportional . Therefore ,

⇒ ED/ CB = AD/AB

⇒ 11/2 = 3 + x / 3

⇒ 33 = 2(3+x)

⇒ 6 + 3x = 33

⇒3x = 33 - 6

⇒ 3x = 27

⇒ x = 27/3

⇒ x = 9
