Answer:

The distance is 5.20m

Step-by-step explanation:

Here, we want to get the height of the ladder

To get this, we need to understand that we have a right triangle, with the base of the triangle as 3 m, the angle at the downward part is 60, and we want to get the height of the triangle

The angle here faces the height we want to calculate

This height is known as the opposite

What we have is the adjacent

Now, the trigonometric identity that relates the opposite and the adjacent is the tan

The tangent of an angle is the ratio of the opposite to the adjacent

Mathematically;

tan 60 = h/3

h = 3 tan 60

h = 5.20 m

The ladder is at a height of 5.20 m above the ground

need help with this Drag the points to create graphs of linear relationships that have different y-intercepts and slopes of 1/5,
ludmilkaskok [199]

Linear relationships that have different y-intercept and slope of 1/5 is y=1/5 x+25/6.

Given that, the slopes are 1/5, 3/5 and 6/5.

<h3>What is slope of a line?</h3>

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The coordinate points from the given figure are (6, 5), (5, 1) and (4, 3).

Substitute m=1/5 and (x, y)=(6, 5) in y=mx+c, we get

5=1/5 ×6+c

⇒ c=5- 5/6

⇒ c=25/6

Put m=1/5 and c=25/6 in y=mx+c, we get

y=1/5 x+25/6

Substitute m=3/5 and (x, y)=(5, 1) in y=mx+c, we get

1=3/5 ×5+c

⇒ c=-2

Put m=3/5 and c=-2 in y=mx+c, we get

y=3/5 x-2

Substitute m=6/5 and (x, y)=(4, 3) in y=mx+c, we get

3=6/5 ×4+c

⇒ c=3-24/5

⇒ c= -9/5

Put m=6/5 and c= -9/5 in y=mx+c, we get

y=6/5 x-9/5

Therefore, linear relationships that have different y-intercept and slope of 1/5 is y=1/5 x+25/6.

What is length of the altitude of the equilateral triangle below?
Lina20 [59]

Answer: OPTION D.

Step-by-step explanation:

Given the equilateral triangle shown in the figure, you need to find the value of the altitude "a".

In order to find the altitude, you can use the following Trigonometric Identity:

tan\alpha =\frac{opposite}{adjacent}

In this case you can identify that:

\alpha=60\°\\\\opposite=a\\\\adjacent=2\sqrt{3}

Therefore, you can substitute values into tan\alpha =\frac{opposite}{adjacent}:

tan(60\°)=\frac{a}{2\sqrt{3}}

Finally, you must solve for the altitude "a". Then, this is:

 (tan(60\°))(2\sqrt{3})=a\\\\a=6

Notice that this result matches with the value shown in Option D.
