Answer:

  ΔLMN ~ ΔLFG; scale factor 7/3

Step-by-step explanation:

The ratios of side lengths, shortest to longest are ...

  FG : GL : LF = 24 : 36 : 42 = 4 : 6 : 7 (reduced)

  MN : NL : LM = 56 : 84 : 98 = 4 : 6 : 7 (reduced)

The side ratios are the same, so ΔLMN ~ ΔLFG. The scale factor is ...

  MN/FG = 56/24 = 7/3

Answer:

State that the triangles in each pair of similar. If so, complete the similarity statement, and find the scale factor for each one. (you may go either direction). NO LINKS!!! Part 1

Step-by-step explanation:

Given

The question is illustrated with the attached image

Required

Find h

To solve for h, we apply tangent formula i.e.

[tex]\tan(\theta) = \frac{Opposite}{Adjacent}[/tex]

This gives:

[tex]\tan(60) = \frac{h}{50}[/tex]

Make h the subject

[tex]h = 50 * \tan(60)[/tex]

[tex]\tan(60) = \sqrt 3[/tex]

So, we have:

[tex]h = 50 * \sqrt 3[/tex]

[tex]h = 50 * 1.7321[/tex]

[tex]h = 86.61m[/tex]

Answer:

[tex]\tan(A) = \frac{3}{5}[/tex]

Step-by-step explanation:

Given

[tex]\sin(A) = \frac{3}{\sqrt {34}}[/tex]

[tex]0 \le A \le 90[/tex] --- First Quadrant

Required

Find tan(A)

The sin of an angle is:

[tex]\tan(A) = \frac{Opposite}{Hypotenuse}[/tex]

and

[tex]\sin(A) = \frac{3}{\sqrt {34}}[/tex]

By comparison:

[tex]Opposite = 3[/tex]

[tex]Hypotenuse = \sqrt{34[/tex]

So, the Adjacent is:

[tex]Hypotenuse^2 = Adjacent^2 + Opposite^2[/tex]

[tex](\sqrt{34})^2 = Adjacent^2 + 3^2[/tex]

[tex]34 = Adjacent^2 + 9[/tex]

Collect like terms

[tex]Adjacent^2 =34 - 9[/tex]

[tex]Adjacent^2 =25[/tex]

Take square roots

[tex]Adjacent =\sqrt{25[/tex]

[tex]Adjacent =5[/tex]

The tangent of an angle is:

[tex]\tan(A) = \frac{Opposite}{Adjacent}[/tex]

This gives:

[tex]\tan(A) = \frac{3}{5}[/tex]

Answer:

2.2 × 10³ mm³

Step-by-step explanation:

We have a triangular prism with the following dimensions:

Altitude: 20.5 millimeters

Base: 16 millimeters

Height: 13.3 millimeters

We can calculate the volume of a triangular prism using the following expression.

V = (1/2 × Altitude × Base) × Height

where,

(1/2 × Altitude × Base) is the area of the base

V = (1/2 × Altitude × Base) × Height

V = (1/2 × 20.5 mm × 16 mm) × 13.3 mm = 2.2 × 10³ mm³

the number of pancake does it make from 3 1/3 cups of pancake is 30 pancakes.

What is proportion ?

A proportion is an equation based on the equality of two ratios.

Here it is given that :

2/3 of a cup of pancake mix makes 6 pancakes

2/3  pancake mix = 6 pancakes

multiply 3/2 both side :

1 pancake mix = 6x3/2 pancakes

1 pancake mix = 9 pancakes

Now to find the number of pancake does it make from 3 1/3 cups of pancake mix multiple 3 1/3 both side That is :

3 1/3  pancake mix = 9 x 10/3 pancakes

3 1/3  pancake mix = 30 pancakes

Therefore, the number of pancake does it make from 3 1/3 cups of pancake is 30 pancakes.

Answer: the answer is c. 13cm, 14cm, 15cm

Step-by-step explanation:

The lengths are 8cm , 15cm and 17 cm

A right angle triangle follows the Pythagorean theorem. Therefore, it should be

where

c = hypotenuse

a and  b are  opposite and adjacent sides.

The hypotenuse is the longest side of a right angle triangle. The 3 lengths that follows this theorem are 8 cm, 15 cm and 17cm.

Answer:

"descends"

Step-by-step explanation:

The word descend means to move or fall downwards. If we were to think of the ladder as the y-axis of a coordinate grid we could see that as you move further down on the axis the numbers turn to negative which indicate that the word descend means that a negative integer should be used :)

Given :

Vector V has components of (6,9).

To Find :

The angle in degrees that vector V makes with the x-axis.

Solution :

The x-component of vector is, x = 6 units.

The y-component of vector is, y = 9 units.

So, the angle the vector makes from the horizon is :

[tex]\theta = tan^{-1}{\dfrac{y}{x}}\\\\\theta = tan^{-1}{\dfrac{9}{6}}\\\\\theta = 56.31^o[/tex]

Hence, this is the required solution.

Answer:

A. Yes

Step-by-step explanation:

I calculated it logically

Yes the given figure with rectangle tessellates the plane.

A rectangle cannot tessellate a plane by itself because it is not a regular polygon with equal angles and sides.

A rectangle can only tessellate the plane if it is combined with other shapes, such as squares or triangles, to form a regular tessellation.

Yes, the given figure tessellates the plane.

Hence, Yes the given figure tessellates the plane.
