5tanx-2cotx+1=0...... .

Verdich [7]

Step-by-step explanation:

5(tanx)^2 -2 +tanx=0

let tanx=y

5y^2 + y-2=0

y=0.5403 or y= -0.7403

tanx=0.5403

x=arctan(0.5403)

x=28.38°

tanx=-0.7403

x=arctan(-0.7403)

x=143.49°

I need help with geometry

olchik [2.2K]

Answer:

m<1=?

m<2=4x-20..........(1)

m<4=3x-11.............(2)

Step-by-step explanation:

we have

m<2=m<4(corresponding angle of parrelelogram are equal)
4x-20=3x-11
4x-3x=20-11
x=9

again.we have

<1+<2=180(co-interior angle)

<1=180-<2=180-(4×9-20)=180-16=164

Ede4ka [16]

Answer:

The actual area of the garden is 1256 square feet.

Step-by-step explanation:

Given:

A gardener is designing a circular garden.

On the blueprint, the garden has a diameter of 16 centimeters.

The blueprint has a scale of two centimeters to five feet.

Now, to find the actual area of the garden.

Let the actual diameter of the garden be $x\ feet.$

And the diameter of the garden on blueprint = $16\ centimeters.$

As, given:

The blueprint has a scale of two centimeters to five feet.

2 centimeters is equivalent to 5 feet.

Thus, 16 centimeters is equivalent to $x\ feet.$

Now, to get the actual diameter by using cross multiplication method:

$\frac{2}{5} =\frac{16}{x}$

By cross multiplying we get:

$2x=80$

Dividing both sides by 2 we get:

$x=40\ feet.$

<em>Thus, the actual diameter of the garden is 40 feet.</em>

Now, to get the area of the garden we get the radius and then put the formula of area:

Radius = $\frac{Diameter}{2}$

Radius(r)= $\frac{40}{2}=20\ feet.$

$Area =\pi r^2.$

$Area=3.14\times 20^2$

$Area=3.14\times 400$

$Area=1256\ square\ feet.$

Therefore, the actual area of the garden is 1256 square feet.
