Answer:

[tex]\theta = 40.59^\circ[/tex]

Step-by-step explanation:

Given

The question is illustrated with the attached image

Required

Find [tex]\theta[/tex]

To do this, we use sine formula

i.e.

[tex]\sin(\theta) = \frac{Opposite}{Hypotenuse}[/tex]

So, we have:

[tex]\sin(\theta) = \frac{10.8}{16.6}[/tex]

[tex]\sin(\theta) = 0.6506[/tex]

Take arc sin

[tex]\theta = \sin^{-1}(0.6506)[/tex]

[tex]\theta = 40.59^\circ[/tex]

Using the tangent ratio, the value of x, to the nearest tenth, is: 5.5.

Given a right triangle with a missing length, x, we have the following:

∅ = 70°

Opposite side length = 15

Adjacent side length = x

The tangent ratio to be applied is:

Tan ∅ = opp/adj

Plug in the values

Tan 70 = 15/x

x(tan 70) = 15

x = 15/tan 70

x ≈ 5.5

Answer:

Find the value of one the subtract it from 180

Step-by-step explanation:

Solve for X in interesting lines by finding the value of one adjacent angle and subtracting it from 180 degrees.

Answer:

X = 10.7

Step-by-step explanation:

25^2 - 16^2 = 369 which squared is approximately 19.2. We need X which is the smaller side so we minus 22^2 from 19.2^2 which is 115.36 which is squared to 10.7

Answer:

y = 4x +2

Step-by-step explanation:

The formula/equation for slope-intercept form is: y=mx+b. M stands for slope and b stands for the y-intercept.

In this question, you're already given the slope, 4, so luckily, you don't need to find that. However, you need to find the y-intercept, or otherwise known as b in the slope-intercept formula.

Given coordinates: (6, 26) ---> (6 is the x-intercept, and 26 is the y-intercept)

Slope: 4

Plug those values into y=mx+b

26 = 4(6) + b

26 = 24 + b

Subtract 24 on both sides to isolate out b.

2 = b

Now that you've found the y-intercept, plug in your stuff to form your slope-intercept equation/formula.

y = 4x + 2

Answer:

B. DE = 58

Step-by-step explanation:

The base angles (<F and <E) of the ∆DEF are congruent/equal. This means that ∆DEF is an isosceles triangle.

This implies that, the two sides (DF and DE) that are opposite to the base angles are congruent/equal.

DE = 40 (given) => option B is INCORRECT

Therefore:

8x - 24 = 40

Solve for x

8x - 24 + 24 = 40 + 24

8x = 64

8x/8 = 64/8

x = 8 (option C is CORRECT)

Let's find DF and FE:

DF = 8x - 24

Plug in the value of x

DF = 8(8) - 24

DF = 64 - 24

DF = 40 (Option D is CORRECT)

FE = 6x + 10

FE = 6(8) + 10

FE = 48 + 10

FE = 58 (Option A is CORRECT)

The only incorrect statement is:

B. DE = 58

Answer:

  x = 20

Step-by-step explanation:

Corresponding sides are proportional:

  x/15 = 24/18

  x = 15(24/18) = 15(4/3)

  x = 20

Answer:

According to the property of corresponding sides

x1/x2 = y1/y2

x/15 = 24/18

x/15 = 4/3

x = 4 × 15/3

x = 4 × 5

x = 20

Answer: The Pacing Method:

Use Edulastic to help convey weekly expectations and track student progress along the way

You can set up Edulastic to function as your check-in-tool with students, and Edulastic will help you in gathering student data during this process (#Edulasticforthewin!). This can help in estimating student participation grades and preparing reports to supervisors. It can also help with pacing and students staying on task.

When I was a high school science teacher I would structure “Check ins” with my students on written handouts that students had to present to me for my signature (upon meeting and discussing project updates, hearing feedback from me etc.). If I had access to Edulastic tools then, I could have instead coordinated these check ins digitally and privately using Edulastic. They could check-in on their own time, at home or at school. That makes things a heck of a lot more efficient than having students form a line waiting to talk to me at my desk! You can set this up to occur at the every other day mark, weekly mark, biweekly, or even monthly mark depending upon length and scope of a project in place.

Check out how this might look in Edulastic:
