360 to 30 can be written as 360:30 and call also be written as 360/30

$\frac{360}{30} = \frac{36 \times 10}{3 \times 10}= \frac{36}{3} = \frac{12 \times 3}{1 \times 3} = \frac{12}{1}$

360 to 30 simplified can be expressed as a ratio like 12:1, 12 to 1, or 12/1

Step-by-step explanation:

This is an arithmetic sequence since there is a common difference between each term. In this case, adding

−

In the accompanying diagram of rectangle ABCD, diagonal AC is drawn, DE = 8, DE 1 AC, and m2 DAC = 55. Find the area of rectangl

Aneli [31]

Answer:

sin (55) = DE / AD

AD = DE / sin (55)

AD = 8 / sin (55)

And

tan (55) = DC / AD

tan (55) = DC / [8 / sin (55) ]

DC = 8 tan (55) / sin (55)

AD * DC =

[8 /sin (55) ] [ 8 tan (55) / sin (55) ] = 136 units^2

If aa skateboard ramp is 15 meters long and it extends 12 meters from the base of the starting point. How high is the ramp?

guapka [62]

The height of the ramp is 9 meter

<u>Solution:</u>

It is given that a skateboard ramp is 15 meters long and it extends 12 meters from the base of the starting point.

If we look at the sum, closely we understand that the ramp is a right angled triangle.

Which has a base length of 12 metres and a hypotenuse of 15 metres.

We need to find its height.

To do so we can use the Pythagoras theorem

Pythagorean theorem, states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.

By above definition, we get

$\text {Hypotenuse}^{2}=\text {height}^{2}+\text { base }^{2}$

Since we already know the lengths of the hypotenuse and base we can substitute them in the formula and solve for the height.

Let height of the ramp be denoted by ‘h’

$\begin{array}{l}{15^{2}=12^{2}+h^{2}} \\\\ {225=144+h^{2}} \\\\ {225-144=h^{2}} \\\\ {81=h^{2}} \\\\ {h=\sqrt{81}} \\\\ {h=9}\end{array}$

Therefore, the height of the ramp is 9 meter
