Answer: The value of ∠K is 56°.
Step-by-step explanation:
Given: A pair of triangles Δ EDC ~ Δ KGH
∠E = 56° and ∠H = 34° .
Since corresponding angles of similar triangles are equal.
⇒∠E = ∠K ...(i)
⇒∠D = ∠G
⇒∠C = ∠H
∠E = 56° [Given]
⇒∠K = 56° [From (i)]
Hence, the value of ∠K is 56°.

to find a use sin =opp/hyp
sin 32=opp or a /hyp
sin 32*hyp=9.53
then to find b you can pythagorean theorem or just use cah or cos =adj/hyp

Tiles with the letters A, B, C, D, E, F, G, and H written on them are placed in a bag. Malik draws out one letter at random. Which statements about the situation are true? Check all that apply.
The number of possible outcomes is 8.
The probability of drawing the tile with E written on it is 1/4
P(vowel) = 1/4
P(vowel) + P(consonant) does not = 1
Choosing one letter at random is a simple event.
Answer:
P(vowel) = [tex]\frac{1}{4}[/tex]
Choosing one letter at random is a simple event.
Step-by-step explanation:
P(vowel) = [tex]\frac{1}{4}[/tex]
This is because there are 2 vowels so the probability [tex]\frac{2}{8}[/tex] is which can be simplified to [tex]\frac{1}{4}[/tex] .
Moreover, Choosing one letter at random is a simple event.
The definition of a simple event is one that can only happen in one way, or in other words, it has a single outcome.
Malik's probability of drawing one letter at random is 1/4.
Probability calculation:P (vowel) = [tex]\bold{ \frac{1}{4}}[/tex] It's good to select one letter at random. P(vowel) = [tex]\bold{ \frac{1}{4}}[/tex]Since there are two vowels, the probability is [tex]\bold{ \frac{2}{8}}[/tex], is equal [tex]\bold{ \frac{1}{4}}[/tex].Furthermore, picking one letter at random is an easy procedure.A simple event is one that can only happen one way or has just one conclusion.Find out more about the probability here:

Charles and Seth are building a ramp for Sasha and Samantha. The base of the triangle is 11ft and it's height is 5ft. How long is the diagonal of the ramp?
Answer: 12.1 ft
Step-by-step explanation:
A ramp represents a right-angled triangle so Pythagorean formula can be used to find the diagonal length which will also be the hypotenuse.
c² = a² + b²
Where:
c = hypotenuse
a = base
b = Height
c² = 11² + 5²
c² = 121 + 25
c² = 146
c = √146
c = 12.1 ft

To measure the width of a river, a ranger sights a tree across a river is about 60 degrees north of east. On the map, her position is marked A. She then walks along the river to position B and sights the same tree at 40 degrees north of west. If each unit on the map is 1 mile, about how many miles from her current position is the tee?
Answer:
35 miles I'm not sure I think my phone is glitching out on the question because It is in a weird format
The approximate distance from the ranger's current position to the tree is 0.652 miles.
To solve this problem, we can use trigonometry and create a diagram based on the given information.
Let's assume the ranger's starting position (marked A) is the origin (0,0) on a coordinate plane, and she walks along the river to position B. We need to find the distance between the ranger's current position and the tree.
Based on the information provided:
The tree is sighted about 60 degrees north of east from position A.
The tree is sighted at 40 degrees north of west from position B.
Now, let's calculate the coordinates of position B. Since each unit on the map is 1 mile, we can assign coordinates (x, y) to position B.
At position B, we can break down the distance into the horizontal and vertical components:
The horizontal distance from A to B is the same as the horizontal distance from B to the tree.
The vertical distance from A to B is the same as the vertical distance from B to the tree.
Let's denote the horizontal distance as d h and the vertical distance as d v.
From position A, we have:
Horizontal component: d h = d * cos(60°)
Vertical component: d v = d * sin(60°)
From position B, we have:
Horizontal component: d h = d * cos(40°)
Vertical component: d v = d * sin(40°)
Since both d h and d v are the same at position B, we can set up the following equation:
d * cos(40°) = d * cos(60°)
Simplifying the equation, we have:
cos(40°) = cos(60°)
To solve for d, we can divide both sides by cos(40°):
d = cos(60°) / cos(40°)
Using a calculator or trigonometric table, we can find the values of cos(60°) and cos(40°):
cos(60°) ≈ 0.5
cos(40°) ≈ 0.766
Substituting these values:
d ≈ 0.5 / 0.766
Calculating the result:
d ≈ 0.652
Therefore, the approximate distance from the ranger's current position to the tree is 0.652 miles.

Find the value of x. If needed round to the nearest tenth (one decimal place)
Answer:
x = 8.7
Step-by-step explanation:
The triangles are congruent, which means that the sides are proportional to each other. Line DE and line BE are proportional to each other. This means that:
8 = 12
We can simplify this down to
2 = 3
Now that we have this proportion we can apply it to Lines AE and EC
2(13) = 3x
26 = 3x
8.67 = x
Therefore x is equal to 8.67 (or 8.7 rounded)
Check:
8/12 = 0.6667
8.6667/13 = 0.6667
Since both are the same, the answer is correct.
I hope this helps!!

The solution to the system of equation y = 2x - 4 and y = 3/2x - 2 is (4, 4).
What is the graphical solution of a system of equations?Graphical solutions of a system of equations are way of finding the intersection points of all the equations given.
A system with two or more than two equations has a solution only when they have a common intersection point.
Given are two equations of a line they are,
4x - 2y = 8⇒ - 2y = - 4x + 8 ⇒ y = 2x - 4 and y = 3/2x - 2.
The intersection of these two lines are (4, 4) and hence it is the solution
