The Angle of depression from the top of the flagpole to an object on the ground it's 33° if the object is 60 feet from the base
N76 [4]

Answer:

The flag pole is 38.96 feet tall.

Step-by-step explanation:

The angle of depression from the top of the flagpole to an object on the ground is 33°.

The object is 60 feet from the base of the cliff.

We need to find the height of the flag pole.

Here, base, B = 60 feet

We know that,

\tan\theta=\dfrac{P}{B}

Put all the values to find P.

P=B\times \tan\theta\\\\P=60\times \tan(33)\\\\P=38.96\ ft

So, the flag pole is 38.96 feet tall.

A rectangle is drawn so the width is 97 inches longer than the height. If the rectangle's diagonal measurement is 113 inches, fi
inn [45]

Step-by-step explanation:

h = height of rectangle (should be "length", but ok)

w = width of rectangle

w = h + 97

the diagonal of the rectangle is the Hypotenuse (baseline) of a right-angled triangle with the legs being one height and one width side of the rectangle.

so, we use Pythagoras

c² = a² + b²

with c being the Hypotenuse (the side opposite of the 90° angle).

diagonal² = h² + (h + 97)² = h² + h² + 2×97h + 97²

113² = 12769 = 2h² + 194h + 9409

3360 = 2h² + 194h

1680 = h² + 97h = (h + 97/2)² - 9409/4

(completing the square)

6720/4 + 9409/4 = (h + 97/2)²

16129/4 = (h + 97/2)²

127/2 = h + 97/2

30/2 = h = 15

the height is 15.0 in

3. In the figure below, E is on AD and C is on BD. The dimensions given are in meters. What is the length, in meters, of CD?
damaskus [11]

Answer:

C. 3,960

Step-by-step explanation:

∆ADB ~ ∆EDC. Therefore,

\frac{AB}{EC} = \frac{DB}{DC}

\frac{2,000}{1,200} = \frac{2,640 + x}{x} (substitution)

Solve for x

\frac{5}{3} = \frac{2,640 + x}{x}

Cross multiply

5*x = 3(2,640 + x)

5x = 7,920 + 3x

5x - 3x = 7,920

2x = 7,920

x = 7,920/2

x = 3,960 meters
