Answer:

BCDA is equivalent to FGHE

A is equivalent to angle E

B is equivalent to angle F

C is equivalent to angle G

D is equivalent to angle H

Step-by-step explanation:

1st step is just figuring out which sides corresponds with which.

A is equivalent to angle E

B is equivalent to angle F

C is equivalent to angle G

D is equivalent to angle H

On the last one I am confused by what it is asking, but here is what I think:

The scale factor from the big figure to the small figure is 1.5 because of 15/10=1.5

12/8=1.5 and so on.

Find the value of X<br> (Simplify your answer. Type an exact answer, using radicals as needed.)

Gala2k [10]

Answer:

11 $\sqrt{2}$

Step-by-step explanation:

The given shape is a right triangle, to find the value of x we can use Euclidian Theorem:

x^2 = 14*(14+4)

x^2 = 280 find the root for both sides

x = 11 $\sqrt{2}$

Pleaseee helppppppppppppppppppp

To find Angle A we use cosine

cos ∅ = adjacent / hypotenuse

From the question

The adjacent is 17

The hypotenuse is 38

So we have

cos A = 17/38

A = cos-¹ 17/38

A = 63.4

<h3>A = 63° to the nearest degree</h3>

To find Angle C we use sine

sin ∅ = opposite / hypotenuse

From the question

The opposite is 17

The hypotenuse is 38

So we have

sin C = 17/38

C = sin-¹ 17/38

C = 26.57

<h3>C = 27° to the nearest degree</h3>

Hope this helps you

Last week, Gina's art teacher mixed 9 pints of red paint with 6 pints of white paint to make pink. Gina mixed 4 pints of red pai

cricket20 [7]

No, in order to do the correct ratio she would have needed to add 4.5 pints to 3 pints because if you divide 9:6 by 2 it is 4.5:3 not 4:3

I need to know what rule represents the enlargement of a figure

Amiraneli [1.4K]

Answer:

The correct option is;

(x, y) → (215·x, 215·y)

Step-by-step explanation:

An enlargement is a form of transformation involving an alteration of the size of the shape. When a shape is to be enlarged, the center of the shape is noted and the enlargement of the dimensions of the shape from that center is by multiplication of each point by the factor of the enlargement or the scale factor.

Therefore, based on the requirement for enlargement, and given the dimension of the point from the center as (x, y) the enlargement then is (215·x, 215·y), where 215 is the scale factor.
