Answer:

The ratio of side lengths is 4:15

The ratio of areas as a fraction is 16/225

Step-by-step explanation:

We can probably assume the triangles are similar. If that is the case, the smaller triangle is 4/15s the size of the blue triangle. That makes the ratio 4:15.

As for the ratio of areas, areas are expressed in length^2. Inches squared, centimeters squared, meters squared, or whatever length. It is always a length squared.

Similarly, the ratio of the length can be squared to give the ratio of the areas. The ratio of the areas is 4^2 / 15^2 = 16/225

posledela

Answer:

4.04 metros

Step-by-step explanation:

Resolvemos la pregunta anterior usando la función trigonométrica de

tan θ = Opuesto / Adyacente

θ = 60 °

Frente = 7 metros

Adyacente =? = x

Por eso

bronceado 60 = 7 / x

Multiplicar cruzada

= tan 60 × x = 7

x = 7 / tan 60

x = 4.0414518843 metros

Aproximadamente = 4.04 metros

A pair of equations is shown below: y = 8x − 9 y = 4x − 1 Part A: Explain how you will solve the pair of equations by substituti
babunello [35]

Answer:

see below

Step-by-step explanation:

y = 8x − 9

y = 4x − 1

Since the two equations are both equal to y set them equal to each other

8x -9 = 4x-1

Subtract 4x from each side

8x - 9 -4x = 4x-1-4x

4x -9 = -1

Add 9 to each side

4x-9+9 = -1+9

4x = 8

Divide by 4

4x/4 = 8/4

x=2

Now find y

y =4x-1

y = 4(2) -1

y = 8-1

y = 7

(2,7)

The solution to the system of equations is where the two lines intersect.  When  the two lines are graphed, they will intersect at (2,7)
