The sail of a boat is in the shape of a right triangle, as shown below:

The sail of a boat is a right triangle with an acute angle equal to 40 degrees and the side adjacent to the 40 degrees angle is

Which expression shows the height, in meters, of the sail? (6 points)

Select one:
a. 2 divided by sec 40 degrees
b. 2 cosec 40°
c. 2 sin 40°
d. 2 divided by cot 40 degrees

Answer:

Yes. (see below)

Step-by-step explanation:

First, find the slope of the line. You can do that by using the slope formula:

      y2 - y1

m = ----------

      x2 - x1

Now, choose any two points from the line to plug in. I'm using the points (0, 3) and (2, 4).

      4 - 3

m = ------

      2 - 0

      1

m = --- = 1/2

      2

Now, to simplify your situation, you can use the slope-intercept formula. To use this, you first need to find the slope and y-intercept.

The y-intercept is where the line meets the y-axis, which is (0, 3), so the y-intercept is 3.

Now, plug them in:

y = mx + b

y = 1/2x + 3

To see if a specific point is on this line—which, in this case, is (20, 13), plug them in and simplify to see if it's true:

13 = 1/2 (20) + 3

13 = 10 + 3

13 = 13

This is true, so the point (20, 13) is on this line.

Its 2 x radius

Step-by-step explanation:

Answer:

Twice the radius length.

Step-by-step explanation:

Generally, the diameter is the length of a line that extends from one point on a circle to another point on a circle as long as that line passes through the center of the circle. Essentially, a diameter, in short, is twice the length of the radius of a circle.

Answer: i believe you're trying to find N, if so N=3

Step-by-step explanation:

you would start by adding +2 to each side of the equation, leaving you with 3n=9

you would then divide each side by 3, which gives you N=3

Answer:

27/100 because if u write the decimal out in word form it's 27 hundredths and its the same thing if u write 27/100 in word form

Answer:

No, A is

Step-by-step explanation:

You can tell by plugging in the numbers. 0 - 3(0) < 1 as 0 < 1.

============================================================

Explanation:

Let's check if choice C is the answer or not

We will plug in x = -2 and y = 1 into the inequality to get

y - 3x < 1

1 - 3(-2) < 1

1 + 6 < 1

7 < 1

That's a false statement since 7 is not smaller than 1. This means the first inequality is false when (x,y) = (-2,1). So we can rule out choice C. Choices B and D are similar stories.

---------------

It turns out that choice A is the answer because

y - 3x < 1

0 - 3(0) < 1

0 - 0 < 1

0 < 1

Which is a true statement. So (x,y) = (0,0) is one solution to this inequality.

I'll let you check the other answer choices. You should find them to be false

i dont know if its right since i havent done trig in ages but

[tex]3 \sqrt{3} [/tex]

Step-by-step explanation:

tan(30)x9?

put the opposite angle inside the () since were doing toa which is tan(sin)=opposite/adj

so if we rearrange the formula to make opposite the subjects its

opposite=tan x adj

this is probably wrong so u might want to check with someone else

Answer:

400

The ladder is the hypotenuse of a right triangle. The 2 feet from the wall on the ground is one side, the distance up the wall is another side.

In a right triangle, the square of the hypotenuse is the sum of the squares of the other two sides. This is called the Pythagorean Theorem. In equation form:

c^2 = a^2 + b^2

Substitute the known values:

20^2 = 2^2 + b^2

Square the numbers:

400 = 4 + b^2

Subtract 4 from both sides:

b^2 = 400 - 4 = 396

Take the square root:

b = sqrt(396) = 19.9 (rounded) feet

Check:

20^2 ?= 2^2 + 19.9^2

400 ?= 4 + 396.01

400 ?= 400.01 (off just a bit due to rounding)
