Using a trigonometric identity, considering the given value of the tangent of theta, the secant of the same angle is given by:

[tex]\sec{\theta} = \pm \sqrt{\frac{11}{8}}[/tex]

According to the following identity:

[tex]\sec^2{\theta} = 1 + \tan^2{\theta}[/tex]

In this problem, the tangent squared is given as follows:

[tex]\tan^2{\theta} = \frac{3}{8}[/tex]

Hence the secant is given by:

[tex]\sec^{2}{\theta} = 1 + \tan^2{\theta}[/tex]

[tex]\sec^{2}{\theta} = 1 + \frac{3}{8}[/tex]

[tex]\sec^{2}{\theta} = \frac{11}{8}[/tex]

[tex]\sec{\theta} = \pm \sqrt{\frac{11}{8}}[/tex]

Answer:

36

Step-by-step explanation:

A ratio 4:6 means the one quantity is 4/10 of the full thing:

While the other quantity is 6/10 of the full thing

So the smaller angle will be 4/10 of the the complementary angle.

Complementary angle is 90.

So 4/10 of 90 is 36.

Answer:

The slope of the line is: M = 0

Step-by-step explanation:

Using the "Slope from 2 points" formula which is \/

M = (y2 - y1) / (x2 - x1)

We just need to input the numbers to find the slope!
M = ( 1 - 1 ) / (1 - - 2 )

Now solve within the parentheses:

M = ( 0 ) / ( 3 )

Which is basically just 0.

I hope the formula: M = ( y2 - y1) / (x2 - x1)

The measure of angle HIJ is 20°. The correct option is the last option 20°

From the question, we are to determine the measure of angle HIJ

From one of the Circle theorems, we have that

The angle at the center of a circle is twice the angle at any part of the circumference

From the information,

The measure of arc HJ is 40°. That is, the angle at the center is 40°.

Then, using the above theorem,

Measure of angle HIJ = 40° / 2

Measure of angle HIJ = 20°

Hence, the measure of angle HIJ is 20°. The correct option is the last option 20°

Radius= 6

Step-by-step explanation:

We use the formula (x-h)^2+(y-k)^2 then plug in our numbers:

[tex](x - h)^2 + (y - k)^2 = r^2\\(x+6)^2 +(y-k)^2=36[/tex]

In the equation -h is 6 so our h (x-coordinate) is -6

In the equation -k is 8 so our k (y-coordinate) is -8

In the equation r^2 is 36 so we take the square root of 36 to get r which is 6.

Step-by-step explanation:

The angle ∠DEF is equal to 90 degrees. Then the triangle ΔDEF will be a right-angle triangle.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function. The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

The angle ∠DEG = 51° and angle ∠GEF = 39°.

Then prove that the triangle ΔDEF will be a right-angle triangle. Then we have

We know that if one angle of the triangle is 90 degrees then the triangle will be named a right-angle triangle.

The sum of the angle ∠DEG and ∠GEF will be

∠DEF = ∠DEG + ∠GEF

∠DEF = 51° + 39°

∠DEF = 90°

Then the triangle ΔDEF will be a right-angle triangle.

Answer:

80 pupils

Step-by-step explanation:

60% of 200 is 120
200 - 120 is 80.

The theoretical probability that the arrow will hit the small square on the upper left is approximately 9.8%. (Option A)

To determine the theoretical probability, we first need to calculate the areas involved. Let's start by finding the area of the entire circular target. The formula for the area of a circle is given by A = π * r², where 'r' is the radius. Plugging in the given radius (36 inches) into the formula:

A_circle = π * (36 inches)² ≈ 4069.73 square inches.

Next, we need to calculate the area of the small square in the upper left corner. Since the square is positioned at a corner of the circle, it forms a quarter of a circle. The area of this quarter circle can be calculated as follows:

A_quarter_circle = ¼ * A_circle. = ¼ * 4069.73 = 1017.43

Now, let's find the area of the square. The formula for the area of a square is A_square = side², where 'side' is the side length. Plugging in the given side length (5 inches) into the formula:

A_square = (5 inches)² = 25 square inches.

However, there are four identical squares inside the quarter circle, so the total area of all the squares combined is:

Total_Area_squares = 4 * A_square.

Now, to calculate the probability of hitting the small square in the upper left corner, we divide the area of that square by the area of the quarter circle:

Probability = (A_square / A_quarter_circle) * 100. = 25 / 1017.43 * 100 =  9.8%.

Hence the correct option is (a).
