Answer:

Explicación paso a paso:

Primero, puede crear ecuaciones como este:

Carmen = x + 4x + 2

Daniel = 4x

Tomas = 9x + 2

Marco = 2

42 = 9x + 2 + x + 4x + 2 + 4x + x

38 = 19x

x = 2

La edad de Marco = 2, entonces:

Daniel = 4 (2) = 8

La edad de Daniel = 8

T = 9 (2) +2

Carmen = 5 (2) +2

La edad de Carmen = 12

entonces La edad de Tomás es = 20

Answer:

La edad de Tomas= 20.

Step-by-step explanation:

Primero, puede crear ecuaciónes como este:

C= x+4x+2

D=4x

T= 9x+2

M=2

42= 9x+2+x+4x+2+4x+x

38= 19x

x= 2

La edad de Marco= 2, entonces:

D= 4(2)= 8

La edad de Daniel=8

T= 9(2)+2

La edad de Tomas= 20

C= 5(2)+2

La edad de Carmen= 12

Consider the two triangles. Triangles A B C and H G I are shown. Angles A C B and H I G are right angles. The length of side A C
zheka24 [161]

Answer:

Both are similar by SAS similarity.

This SAS similarity is equivalent to the congruence.

Step-by-step explanation:

Step 1:

To prove that ACB and HIG as similar triangles.

We have to look upon the corresponding sides.

SAS= Side angle sides , there the angle must be in between two sides.

\angle ACB = \angle HIG

Lets work on the corresponding sides.

IG/AC = IH/AC

\frac{9}{15} = \frac{12}{20}

Reducing each to lowest form, we divide numerator and denominator by 3 for the 1st fraction and by 4 for the 2nd fraction.

We have

\frac{3}{5} = \frac{3}{5}

Both sides are equal.

So its proved that both are similar with SAS similarity theorem.

Use calculations and words to show<br>this quadrilateral meets the<br>definition of a kite.❤​
Y_Kistochka [10]

Answer:

Step-by-step explanation:

A kite is a quadrilateral that has only one line of symmetry, and bisecting diagonals.

From the graph,

AB = 6 units

BC = 8 units

CD = 8 units

AD = 6 units

i. Has exactly one pair of congruent sides. Examples are; AB = AD and BC = CD.

ii. The diagonals are perpendicular. AC is at right angle to DB.

iii. The diagonals bisect each other. AC bisects DB, or vice versa.

Therefore, quadrilateral ABCD is a kite.
