Step-by-step explanation:

The value of h is 8 units.

"Two triangles are similar when their corresponding sides are in proportion and all corresponding angles are equal."

For given question,

ΔBAD and ΔCBD are similar triangle.

So, their sides are in proportion.

[tex]\Rightarrow \frac{BA}{CB}= \frac{AD}{BD}= \frac{BD}{CD}[/tex]                    ..................(i)

For given figure,

BD = h, CD = 4 units

Now, we find the length of the side AD.

⇒ AD = AC - CD

⇒ AD = 20 - 4

⇒ AD = 16 units

From (i),

[tex]\Rightarrow \frac{AD}{BD}= \frac{BD}{CD} \\\\\Rightarrow \frac{16}{h} =\frac{h}{4}\\\\ \Rightarrow 16\times 4=h\times h\\\\\Rightarrow h^2=64\\\\\Rightarrow h=8[/tex]

Therefore, the value of h is 8 units.

Step-by-step explanation:

Answer:

Area of the composite figure = 175.1 square units

Step-by-step explanation:

Area of the composite figure given in the picture = Area of the parallelogram + Area of the semicircle formed on one side of the parallelogram

Area of the parallelogram = Base × Height

                                           = 30 × 5

                                           = 150 square units

Area of the semicircle = [tex]\frac{1}{2}(\pi r^{2})[/tex]

                                     = [tex]\frac{1}{2}(\pi)(\frac{8}{2})^{2}[/tex]

                                     = 8π

                                     = 25.13

                                     ≈ 25.1 square units

Now area of the complete figure = 150 + 25.1

                                                       = 175.1 square units

Answer: quantitative

Step-by-step explanation:

Measured variables in statistics may be subdivided into quantitative or Qualitative variables depending on whether the variable in question is numeric or non-numeric. Variables which are designed to evaluate on the basis of Number or quantity may be termed as quantitative variables while those which measure attribute and are used for characterization are called Qualitative variables. In the scenario above, the variable is concerned with the determination of concentration of nitrogen draining into water bodies, concentration follows that numeric calculations be Made in other to determine the amount of nitrogen in milligram per Litre in a particular water body in other to prevent its effect on wildlife which could result from excessive concentration in water bodies.

Got it right on edg. Hope this helps!

Answer:

X = -6

1. 3x + 9 = 5x + 21

2. Subtract -5x from both sides

3x + 9 - 5x = 5x + 21 - 5x

3.-2x + 9 = 21

4. Subtract 9 from both sides

-2x + 9 - 9 = 21 - 9

5.-2x = 12

6. Divide both sides by -2

-2x/-2 = 12/-2

Angle of elevation = 73°

Horizontal distance from foot of ladder to bottom of wall = x feets

Height of ladder = 14 feets

The horizontal distance, x :

Using trigonometry :

Tan θ = opposite / Adjacent

Tan θ = 14 / x

Tan 73 = 14 / x

3.2708526 * x = 14

x = 14 / 3.2708526

x = 4.2802295

x = 4.3 feets
