Find the values of A and B. The diagram is not drawn to scale.

Montano1993 [528]

A = 180 - 36 = 144

b = 360 - (113 + 36 + 144)
b = 60 -293
b = 67

Show that the angles of an equalateral triangle are 60°each

topjm [15]

Answer:

For an equilateral triangle, we know that all 3 sides of the triangle are equal. Accordingly, all the 3 sides of the equilateral triangle hold equal angles.

Since, we know, that the sum of all angles of any triangle be 180° .

Let each angle be a.

Thus,

Hence, we can show that all the 3 angles of an equilateral triangle hold equal angles; i.e. 60°.

Which figure represents an undefined term?

notka56 [123]

In geometry, an undefined term is a basic figure that cannot be defined in terms of other figures.
The undefined terms in geometry are: point, line and plane.

Since you have not attached any figures, I cannot tell you which one is correct. Just choose the figure that is either a point, a line or a plane.

Mito bakes biscuits. he uses 1/4 cup of flour to coat the countertop and the rolling pin. He also uses 2 1/2 cups of flour for e

Gennadij [26K]

Answer:

Mito can bake 3 batches of cookies.

The amount of flour used to bake cookies = Total flour used - Amount of flour used to coven counter top.

Step-by-step explanation:

Here, the amount of flour used to coat counter top and rolling pin = 1/4 cup

1/4 cup = 0.25 cup

Now, the amount of cup used to bake 1 batch of cookies = 2 1/2 cup

Now, 2 1/2 cup = ( 2 + 1/2 )cup = 2 + 0.5 = 2.5 cup

So, 1 batch of cookies = 2.5 cup

Total amount of flour used = 7 3/4 cups

Now, 7 3/4 cup = (7 + 3/4) cup = 7 + 0.75 = 7.75 cups

The actual amount of flour used to bake cookies

= Total flour used - Amount of flour used to coven counter top.

= 7.75 cup - 0.25 cup = 7.5 cup

Now, the number of batches baked with 7.5 cup $= \frac{\textrm{Total amount of flour used in baking}}{\textrm{Flour used in 1 batch}}$

$= \frac{7.5}{2.5} = 3$

or, the number of batches baked with 7.5 cup is 3 batches.

Hence, Mito can bake 3 batches of cookies.

Entre Celia y Quique suman 14€. Si Celia tuviera 1 €, tendría el doble de dinero que Quique.¿ Cuanto dinero tiene cada uno?

denpristay [2]

Answer:

La cantidad de dinero

Celia tiene = x = 9.33 €

Quique tiene = y = 4.67 €

Step-by-step explanation:

Representemos la cantidad de dinero

Celia tiene = x

Quique tiene = y

Entre Celia y Quique suman 14 €.

x + y = 14

x = 14 - y

Si Celia tuviera 1 euro, tendría el doble de dinero que Quique.

Por lo tanto,

x = 2 años

Nosotros sustituimos

2y + y = 14

3 años = 14

y = 14/3

y = 4.67 €

x = 14 € - y

x = 14 € - 4.67 €

x = 9.33 €

Por lo tanto,

La cantidad de dinero

Celia tiene = x = 9.33 €

Quique tiene = y = 4.67 €
