For the two right triangles above, explain why a/8=x/12 . What trigonometric ratio is also equal to the two given ratios?

frutty [35]

Answer:

sin trigonometry ratio

Step-by-step explanation:

Given

See attachment for triangles

Required

Explain why $\frac{a}{8} = \frac{x}{12}$

From the attached diagram, both triangles are similar triangles because

(1) the second triangle is a dilation of the first triangle by a ratio of 1.5

i.e

$k = \frac{12}{8}$

$k = 1.5$

(2) They have angle 30 degrees, and have their right angles located at the same point

In the first triangle, the sine of 30 degrees is represented as:

$sin(30) = \frac{Opp}{Hyp}$

This gives:

$sin(30) = \frac{a}{8}$

In the second triangle:

$sin(30) = \frac{Opp}{Hyp}$

So:

$sin(30) = \frac{x}{12}$

By comparison:

$sin(30) = sin(3)$

Hence:

$\frac{a}{8} = \frac{x}{12}$

Solve this equation for x in terms of y and z:

Alex Ar [27]

3y = 3 * 9 = 27
4z = 4 * -12 = -48
: -48 + 27 = -21
: -21 + x = 24
: X = 45.
I hope that makes sense.

Bridget takes a 5-inch by 4-inch rectangle of fabric and cuts from one corner of the piece of fabric to the diagonally opposite

mario62 [17]

Answer:

Perimeter of each triangles are equivalent to 15.4 inches.

Step-by-step explanation:

Given:

A rectangle :

Length of the rectangle = 5 inches

Width of the rectangle =4 inches

As Bridget cuts it from one corner to the other corner,its forms two right angled triangle.

The diagonal will be treated as the hypotenuse.

Lets say that the length of the hypotenuse is 'x'.

Using Pythagoras formula:

⇒ $(hypotenuse) = \sqrt{(perpendicular)^2+(base)^2}$

Plugging the values:

⇒ $hypotenuse = \sqrt{5^2+4^2}$

⇒ $hypotenuse = \sqrt{25+16}$

⇒ $hypotenuse =\sqrt{41}$

⇒ $hypotenuse = 6.40$ inches

Now we have to find the perimeter :

Perimeter = Summation of length of all sides.

So,

Perimeter of each triangle = (length + width + hypotenuse)

⇒ $Perimeter =(5+4+6.4)$

⇒ $Perimeter =15.4$ inches

Perimeter of each triangle, as they are equally sized are same that is 15.4 inches.
