Answer:

The answer is 28

Step-by-step explanation:

15 divided by 10 is 1.5,

42 divided by 1.5 equals 28,

hence the answer is 28.

Answer: x = 28 unit

Step-by-step explanation:

Here, In triangle APR,

CD ║ AP,

Such that, C ∈ AR and D ∈ PR,

Also, AC = 10 unit, CR = x unit, PD = 15 unit and DR = 42 unit,

Since, CD ║ AP,

Thus, by the alternative interior angle theorem,

\angle APR\cong \angle CDR

\angle PAR\cong \angle DCR

Thus, By AA similarity postulate,

\triangle APR\sim \triangle CDR

Since, the corresponding sides of the similar triangle are in same proportion,

\implies \frac{AR}{CR}=\frac{PR}{DR}

\implies \frac{AC+CR}{CR}=\frac{PD+DR}{DR}

\implies \frac{10+x}{x}=\frac{15+42}{42}

\implies 420 + 42 x = 15 x + 42 x

\implies 420 = 57 x - 42 x

\implies 420 = 15 x\implies 28 = x

Hence, the value of x = 28.

In a 30° - 60° - 90° right triangle, the hypotenuse has a length of 8. what is the length of the longer leg?
Tatiana [17]
Sin 30° = 1/2 = x/8
then x = 4

sin 60° = √3/2 = y/8
then y = 4√3

so the length of the longer leg is 4√3

devlian [24]

Answer:  B. Parent's marital status

The sociology is the study of different aspects of the human society. An explanatory variable is the one which can explain a particular condition or attribute in a study. In the given study the parent's marital status is the explanatory variable. The parent's marital status can influence the married life of their children. The children can be either satisfied or unsatisfied by their marriage because of the influence of the parents. For example, if the parent is single divorced or widow the parent may likely to interfere in the life of the married children in decision making and this likely to cause disputes between the married couple.

Please help me solve 5 and 6 for my homework

Answer:

(5) The perpendicular height of the triangle is 8.48 mm.

(6) The 1184.86 cm far up the wall the ladder reach.

Step-by-step explanation:

Part (5):

When a perpendicular is drawn in an isosceles triangle then the perpendicular divided the base into 2 equal parts.

The figures is shown below.

In ΔABC,

CB = 6 mm

So,

CD = BD = 3 mm

Now calculating the perpendicular height of the triangle.

Using Pythagoras theorem in ΔADC:

(AC)^2=(CD)^2+(AD)^2\\\\(9)^2=(3)^2+(AD)^2\\\\81=9+(AD)^2\\\\(AD)^2=81-9\\\\(AD)^2=72\\\\AD=8.48mm

Thus, the perpendicular height of the triangle is 8.48 mm.

Part (6):

The figure is shown below.

Converting meter to centimeter:

1 m = 100 cm

So,

12 m = 1200 cm

Using Pythagoras theorem in ΔXYZ:

(XZ)^2=(YZ)^2+(XY)^2\\\\(1200)^2=(190)^2+(XY)^2\\\\1440000=36100+(XY)^2\\\\(XY)^2=1440000-36100\\\\(XY)^2=1403900\\\\XY=1184.86cm

Thus, 1184.86 cm far up the wall the ladder reach.

Setler79 [48]

Answer:

65 square units

Step-by-step explanation:

The area of a triangle is: height times base divided by two.

So the area of one of the triangles is 10 square units.

multiply this times 4 to get the total area of the triangles

then add the area of the square which is 5 times 5

25 plus 40 = 65 square units
