What is the sum of the measures of the exterior angles of a quadrilateral? If
necessary, round to the nearest tenth.

Answers

Answer 1

The sum of the measures of the interior angles of a quadrilateral is 360°. The sum of the measures of the exterior angles of a quadrilateral is 360°.

What is a quadrilateral?

A quadrilateral is a closed shape that has four sides, four vertices, and four angles. It's made by connecting four non-collinear points. The sum of quadrilateral interior angles is always 360 degrees.

Assume that ABCD is a quadrilateral.

The sum of the interior angle and the corresponding exterior angle is 180°.

The exterior angle of A is E. The exterior angle of B is F. The exterior angle of C is G. The exterior angle of D is H.

Thus ∠A + ∠E = 180°  .....(i)

∠B + ∠F = 180°  ......(ii)

∠C + ∠G = 180° ......(iii)

∠D + ∠H = 180° ......(iv)

Add equations (i), (ii), (iii), (iv):

∠A + ∠E + ∠B + ∠F + ∠C + ∠G +  ∠D + ∠H = 180°+180°+180°+180°

(∠A+∠B + ∠C +∠D) + ∠E +∠F +  ∠G + ∠H = 720°

The sum of all interior angles of quadrilateral is ∠A+∠B + ∠C +∠D = 360°.

360°+  ∠E +∠F +  ∠G + ∠H = 720°

∠E +∠F +  ∠G + ∠H = 720° - 360°

∠E +∠F +  ∠G + ∠H =  360°

um sapato é vendido a r$ 180,00. se a compra for a vista a loja oferece um desconto de 10%. qual o valordo sapato na compra a vista?​

Answers

Preço de um sapato = $ 180,00

Desconto concedido se o sapato for comprado em dinheiro = 10%

Custo do calçado quando comprado à vista :

[tex] =\tt 180 - 10\% \: \: de \: \: 180[/tex]

[tex] = \tt180 - \frac{10}{100} \times 180[/tex]

[tex] =\tt180 - \frac{10 \times 180}{100} [/tex]

[tex] = \tt180 - \frac{1800}{100} [/tex]

[tex] =\tt 180 - 18[/tex]

[tex]\color{plum} =\tt\$162.00[/tex]

▪︎Assim, preço do sapato quando comprado em dinheiro = $ 162,00

m + 1 = 8

But what’s the m=__

Answers

Answer:m= 7.

Step-by-step explanation: first you do 8-1. 8-1 gives you 7. Therefore m=7

Answer: m = 7

Explanation: When you're asked to solve for m in an equation, what you're really being asked to do is to get m by itself on one side of the equation.

In this problem, since 1 is being added to m, in order to get m

by itself, we must subtract 1 from the left side of the equation.

If we subtract 1 from the left side of the equation, remember that

we must also subtract 1 from the right side of the equation.

So on the left, +1 and -1 cancel each other out

and on the right, 8 - 1 simplifies to 7.

So m = 7.

Each plate is 12 inches in diameter, with gold trim along the edge. How much gold trim is needed in total to prepare the plates? Use 3.14 for pi.




A) 4748 inches
B) 3784 inches
C) 2894 inches
D) 3768 inches

Answers

Answer:

D) 3768 inches

Step-by-step explanation:

Given,

No. of plates = 100

Diameter of each plate = 12inches

So, radius of each plate = 12 / 2 = 6 inches

So, circumference of each plate

[tex] = 2\pi \: r[/tex]

= 2 × 3.14 × 6 inches

= 37.68 inches

Hence, circumference of 100 plates = 100 × 37.68 inches

= 3768 inches

Hence, 3768 inches of gold trim is required (Ans)

Answers

Answer:

C

Step-by-step explanation:

Comment

This is called the difference of squares. Both sides of the minus sigh must be perfect squares or able to be factored in such a way that you are left with perfect squares.  36x^2 is a perfect square. If you take its square root, you get √36x^2 or 6x. That makes B and D incorrect. So what about A and C?

A:The left side of 36x^2 is correct, but the right side is not. The left side of 36x^2 has a square root of 6x.

The right side has been left alone and it shouldn't be.

The 9 is a perfect square. Its square root is 3. That makes C the answer.
