Answer:

A 12

Step-by-step explanation:

We can use the pythagorean theorem to find the length a

a^2 + b^2 = c^2

a^2 + (4sqrt(3))^2 = (8sqrt(3))^2

a^2 +16*3 = 64*3

a^2 +48 = 192

Subtract 48 from each side

a^2 +48-48 = 192-48

a^2 =144

Taking the square root of each side

sqrt(a^2) = sqrt(144)

a = 12

We only take the positive square root because length must be positive

A. 27.
we can prove that the two triangles within the triangle are congruent (the triangle is an isosceles) with SAS. then we do 180- (63 x 2). then we get the top angle. and then we divide 54 by 2 to make the individual angles and then we get 27.

I need #2, #3, #4, #7, and #8.<br> but do as much as you can pls thanks !

Answer:

See explanation.

Step-by-step explanation:

2) Your written answer is correct, y = x +4

3) Slope of perpendicular line: 5/2

y=mx+b

4 = (5/2)(4) + b

4 = 10 + b

b = -6

So, y=(5/2)x - 6

4) Slope of perpendicular line: 1

y=mx+b

5 = (1)(4) + b

5 = 4 + b

b = 1

So, y = x + 1

7) Slope of perpendicular line: 3/4

y=mx+b

4 = (3/4)(4) + b

4 = 3 + b

b = 1

So, y = (3/4)x + 1

8) Slope of perpendicular line: 1/4

y=mx+b

-2 = (1/4)(0) + b

b = -2

So, y = (1/4)x - 2

What is 3:120 equivalent to

fenix001 [56]

1:40 because if we think of this just like a fraction $\frac{3}{120}$ that simplifys down to $\frac{1}{40}$ and because fraction simplifications are similar (related to each other) we can concur that these would be too.

Enjoy!=)

Furkat [3]

Answer:

The length of Ms. Ford's kitchen is 57.5 feet.

Step-by-step explanation:

1. You have the following information given in the problem above:

- The kitchen is rectangular.

- Ms. Ford wants to buy 5 extra feet of wallpaper border.

- She buys a total of 62.5 feet of wallpaper border.

2. Therefore, to calculate the length of Ms. Ford's kitchen, you only need to substract 62.5 feet and the 5 extra feet of wallpaper border. Therefore, the result is:

$62.5ft-5ft=57.5ft$

X-3/35=2/15 please help me and answer it with an explanation

-BARSIC- [3]

I believe x = 23/105 because you would have to add 3/35 to both sides and when you add 2/15 to 3/35 you get an answer of 23/105.

Hope this helps!
