Answer:

42\text{ ft}^2

Step-by-step explanation:

We have been given an image of a composite figure and we are asked to find the carpet needed to cover the hole.

We will divide our given figure in 3 parts as shown in the attachment.

The area of our composite figure will be equal to area of a trapezoid plus area of rectangle plus are of triangle.

\text{Area of rectangle}=7\text{ ft}\times 3\text{ ft}

\text{Area of rectangle}=21\text{ ft}^2

\text{Area of trapezoid}=\frac{6\text{ ft}+3\text{ ft}}{2}\times 4\text{ ft}

\text{Area of trapezoid}=9\text{ ft}\times 2\text{ ft}

\text{Area of trapezoid}=18\text{ ft}^2

\text{Area of triangle}=\frac{2\text{ ft}\times 3\text{ ft}}{2}

\text{Area of triangle}=3\text{ ft}^2

\text{Total area of composite figure}=21\text{ ft}^2+18\text{ ft}^2+3\text{ ft}^2

\text{Total area of composite figure}=42\text{ ft}^2

Therefore, the total area of the composite figure is 42 square feet.

Answer:

Tan C = 3/4

Step-by-step explanation:

Given-

∠ A = 90°, sin C = 3 / 5

<u>METHOD - I</u>

<u><em>Sin² C + Cos² C = 1</em></u>

Cos² C = 1 - Sin² C

Cos² C = 1 - \frac{9}{25}

Cos² C = \frac{25 - 9}{25}

Cos² C = \frac{16}{25}

Cos C = \sqrt{\frac{16}{25} }

Cos C = \frac{4}{5}

As we know that

Tan C = \frac{Sin C}{Cos C }

<em>Tan C = \frac{\frac{3}{5} }{\frac{4}{5} }</em>

<em>Tan C = \frac{3}{4}</em>

<u>METHOD - II</u>

Given Sin C = \frac{3}{5} = \frac{Height}{Hypotenuse}

therefore,  

AB ( Height ) = 3; BC ( Hypotenuse) = 5

<em>∵ ΔABC is Right triangle.</em>

<em>∴ By Pythagorean Theorem-</em>

<em>AB² + AC² = BC²</em>

<em>AC² </em><em>= </em><em>BC² </em><em>- </em><em> AB</em><em>² </em>

<em>AC² = 5² - 3²</em>

<em>AC² = 25 - 9</em>

<em>AC² = 16</em>

<em>AC  ( Base) = 4</em>

<em>Since, </em>

<em>Tan C = \frac{Height}{Base}</em>

<em>Tan C = \frac{AB}{AC}</em>

<em>Hence Tan C = \frac{3}{4}</em>
