Answer:

x ≈ 9.6

Step-by-step explanation:

Δ ABC is right with ∠ C = 90° ( angle between tangent and radius )

Using Pythagoras' identity in the right triangle

x² + 14² = 17²

x² + 196 = 289 ( subtract 196 from both sides )

x² = 93 ( take the square root of both sides )

x = $\sqrt{93}$ ≈ 9.6 ( to the nearest tenth )

Two thirds of the families in smithville own their own homes. The total number of home owning families there is 480. How many fa

Leviafan [203]

X- the total number of families in Smithville.
(2/3)x - the number of home owning families.
At the same time, the number of home owning families is 480.

(2/3)x=480
x=480*3/2=720.

720 families live in Smithville.

Each person would get $\frac{5}{8}$ pizza.

Solution:

Total quantity of pizza = $1\frac{7}{8}$

Number of persons shared = 3

To find how much pizza would each person get:

Let us first convert improper fraction into mixed fraction.

$$1\frac{7}{8}=\frac{1\times8 + 7}{8}=\frac{15}{8}$

Now divide the total quantity of pizza by the number persons shared.

$$\text{Quantity of pizza each person get}=\frac{(\frac{15}{8}) }{3}$

$$=\frac{15}{8\times3}$

$$=\frac{15}{24}$

Divide both numerator and denominator by 3.

$$=\frac{15\div3}{24\div3}$

$$=\frac{5}{8}$

Quantity of pizza each person get = $\frac{5}{8}$

Hence each person would get $\frac{5}{8}$ pizza.

Find the angle of elevation of the sun when a 12.5 meter tall telephone pole casts an 18 meter

MAVERICK [17]

To answer this problem, you should know the formula that we will be using and this would be:
Angle of elevation = arc tan( (vertical height)/(length of the shadow)).

Plugging in the values in the formula. Here, this angle is:

arc tan (12.5/18) = 34.78 degrees

The answer would be approximately 34.78 degrees
