Can someone please help me with this?

Answer:

e = 29.0 will be the answer.

Step-by-step explanation:

Use the sine rule in the given triangle,

\frac{EF}{\text{sin}(\angle D)}=\frac{DE}{\text{sin}(\angle F)}=\frac{DF}{\text{sin}(\angle E)}

\frac{d}{\text{sin}(35)}=\frac{16}{\text{sin}(30)}=\frac{e}{\text{sin}(115)}

d=\frac{16\times \text{sin}(35)}{\text{sin}(30)}

d = 18.35

\frac{16}{\text{sin}(30)}=\frac{e}{\text{sin}(115)}

e=\frac{16\times \text{sin}(115)}{\text{sin}(30)}

e = 29.002

e ≈ 29.0

Therefore, e = 29.0 will be the answer.

4 EZ GEOMETRY QUESTIONS FOR 20 POINTS!
MatroZZZ [7]

Answer:

1. use the formula

(n-2)180

(20 - 2)180\\18 * 180 = 3240

2. use the formula

360/n\\360/12\\n = 30

3. There is only one at 360 degrees

4. there are 6 rotational symmetries and the number of reflectional symmetries would be 6 as you can see:

Use the given conditions to write an equation for the line in point-slope form.
Alex17521 [72]

Step-by-step explanation:

Hey there!

The given slope is; 3. And passing through point (-7,8).

Now,

Using one point formula.

(y - y1) = m(x - x1)

Put all values to find equation.

(y - 8) = 3(x + 7)

Simplify them to get answer.

(y - 8 )= 3x + 21

3x - y + 21 + 8 = 0

3x - y + 29 = 0

Therefore the required equation is 3x-y+29=0.

Find the length of the segment that joins the points (-5, 4) and (6,-3).
Helen [10]

Answer:

\boxed {\boxed {\sf d=\sqrt{170} \ or \  d\approx 13.04}}}

Step-by-step explanation:

We are asked to find the length of a segment or the <em>distance</em> between the 2 points. The formula for distance is:

d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2

where (x₁ y₁) and (x₂, y₂) are the points. We are given the points ( -5, 4) and (6, -3). If we match the number and the corresponding variable, it is:

  • x₁= -5
  • y₁= 4
  • x₂= 6
  • y₂ = -3

Substitute the values into the formula.

d= \sqrt{(6--5)^2+(-3-4)^2

Solve inside the parentheses.

  • 6--5 (Back to back negative signs become a positive)= 6+5 =11
  • -3-4= -7

d= \sqrt{(11)^2+(-7)^2

Solve the exponents.

  • (11)²= 11*11= 121
  • (-7)²= -7*-7= 49

d= \sqrt {(121)+(49)

Add.

d= \sqrt {170}

d=13.0384048104

Even though it's not specified, we could round to the nearest hundredth to make the answer more concise. The 8 in the thousandth place tells us to round the 3 to a 4 in the hundredth place.

  • 13.03<u>8</u>4048104

d\approx 13.04

The length of the segment is <u>√170</u> or approximately <u>13.04. </u>

Define like terms. Please and thank you.
Step2247 [10]
Like terms: in the case of exponents, the same exponents for different numbers
Like 7x and 8x are like terms.
5x and 6x^2 would be unlike terms
Get it??
Good luck~~
