The total area of section 2 is 10.5 unit² which is the correct answer and is option B.

In the given graph, Section 2 has coordinates (2,0), (2,5), (5,0), and (5,2).

So, dividing section 2 into a right-angled triangle and a rectangle.

The right-angled triangle has coordinates (2,2), (2,5), and (5,2) with base = 3 units and height = 3 units.

The rectangle has coordinates (2,0), (2,2), (5,0), and (5,2) with length = 3 units and height = 2 units

So total area = area of right-angled triangle + area of rectangle

⇒ 1/2(base × height) + (length × height)

⇒ (1/2 × 3 × 3) + (3 × 2)

⇒ 1/2(9) + (6) = 4.5 + 6 = 10.5 unit²

Answer:

$\cos 60= (1)/(2)$

$\tan 60 = √(3)$

Step-by-step explanation:

See the diagram given with the question first.

Here we are given a right triangle with two angles other than the right angle are 60° and 30°.

The length of the side opposite to 30° is 4 and the side opposite to 60° is 4√3 and automatically the length of the hypotenuse is 8.

Now, $\cos 60= (Base)/(Hypotenuse) = (4)/(8) = (1)/(2)$

Again. $\tan 60 = (Perpendicular)/(Base) =(4√(3) )/(4) =√(3)$

What is the percent of 5/9

Answers

To write a fraction as a percent, first remember that a percent is a ratio of a number to 100. If we wanted to write $(5)/(9)$ as a percent, we need to find a fraction equivalent to $(5)/(9)$ with a 100 in the denominator of the fraction. We can do this by setting up a proportion.

$(5)/(9)$ = $(n)/(100)$

Now, we can use cross products to find the missing value.

9n = 500

÷9 ÷9

n = 55.6

Therefore, 5/9 can be written as 55.6%.

There are 55.56% of the percent of 5/9.

Since, A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

We have to given that;

To find the percent of 5/9.

Let us assume that,

the percent of 5/9 is, x

Hence, We can formulate;

⇒ 5/9 = x%

⇒ 5/9 = x / 100

⇒ x = 500/9

⇒ x = 55.56%

Thus, There are 55.56% of the percent of 5/9.
