Readme [11.4K]

Answer:

Nate is in Group 2.

Step-by-step explanation:

Total number of students is 24.

These 24 students are divided equally among 4 groups.

Compute the number of students in each group:

Number of students in each group =\frac{24}{4}=6

Thus, there will be 6 groups.

Now the students are numbered with the first student in the first group numbered as 1.

The groups will be:

Group 1: 1, 2, 3, 4, 5, 6

Group 2: 7, 8, 9, 10, 11, 12

Group 3: 13, 14, 15, 16, 17, 18

Group 4: 19, 20, 21, 22, 23, 24

It is provided that Nate is the 11th student.

Then Nate is in group 2.

A wall with a height of 20 feet is braced with a support post that forms a 30 degree angle with the top of the wall. What is the
dexar [7]

The length of the support post is 40 ft.

<u>Solution:</u>

Given, the height of the wall is 20 ft; support post forms 30 degree

Refer the attached image

Let us name the triangle as ABC where AB is the wall (opposite side) of 20 ft and \angle A is 30 degree (\theta) and AC is the length of the post.

To find: The length of the post (AC)

we know the formula, sin\theta=\frac{opp}{hyp} (trigonometric formula)

On substituting the values we get,

\Rightarrow sin(30^{\circ})=\frac{20}{AC}

The value of sin 30 degree is 0.5

\Rightarrow 0.5=\frac{20}{AC}\rightarrow AC=\frac{20}{0.5}\rightarrow AC=40 ft
