The value of the sine of angle D to the nearest hundredth will be 0.25.
What is the sine law?The Law of Sines The law of trigonometric functions, sine law, sine formula, or sinusoidal rule is a trigonometric equation that relates the sizes of any triangle's edges to the sines of its orientations.
The sine law in the triangle ΔCDE is given as,
CD / sin E = DE / sin C = EC / sin D
In triangle ΔCED, the measure of angle ∠E = 90°, ED = 63, DC = 65, and CE = 16. Then we have
65 / sin 90° = 63 / sin C = 16 / sinD
Compare the first and the last term, then we have
65 / sin 90° = 16 / sin D
65 = 16 / sin D
sin D = 16 / 65
D = 14.25°
The worth of the sine of point D to the closest 100th will be 0.25.

1. Point D (9,-8)
is
reflected to D' (9.8).
X axis or y axis
Answer:
X-Axis
Step-by-step explanation:
The Y changed from negative to positive meaning that it reflected across the X-Axis
(っ◔◡◔)っ ♥ Hope It Helps ♥
Answer:
x axis
Step-by-step explanation:
Since the x value stayed the same and the y value changed, we can tell that the point was reflected over the x axis.
Another way to think of it:
If you draw a graph and put both points on the graph, try to fold the paper on one of the axis's. Whichever fold causes the two points to touch, is the axis that point D was reflected on.
Priscilla received 240 votes in the election for student council president. That was 60% of the students who voted in the election. How many students voted in the election? *
Answer:
400 students voted in the election
Step-by-step explanation:
Given:
Total number of votes received by Priscilla = 240
This was 60% of the students who voted in the election.
To find: Total number of students who voted in the election
Solution:
Total number of votes received by Priscilla = 60% of Total number of students who voted in the election
240 = 60% of Total number of students who voted in the election
240 = [tex]\frac{60}{100}[/tex] × Total number of students who voted in the election
So,
Total number of students who voted in the election [tex]=\frac{240(100)}{60}=400[/tex]
A scale drawing of a dance floor is shown. What is the area of the actual dance floor? 22 cmon the top and bottom and 14 cm on the sides 5 cm equals 8 feet
Answer:
The area of the dance floor will be 788.48ft²
Step-by-step explanation:
Since 5cm represents 8ft, it means
1cm represents 8/5ft.
The scale length is 22cm, therefore the actual length would be
22 x 8/5ft = 35.2ft
The scale breadth is 14cm, therefore the actual breadth would be
14 x 8/5ft = 22.4ft
The area of the dance floor will be
(35.2ft)(22.4ft) = 788.48ft²

Evaluate y=x/7+15 when y=21
Answer:
x = 42
Step-by-step explanation:
y = x/7 + 15 ; y = 21
21 = x/7 + 15
21 - 15 = x/7
6 = x/7
x = 6 × 7
x = 42

Answer:
180
Step-by-step explanation:
It wants me to find m∠2 from this
Answer:
Alternate interior angles have the same measure. As we know that 'angle 1 ' and 50° are alternate interior angles hence they must be equal. Also we now that sum of all the angles of a triangle is equal to 180°. Hence, m∠2=15°
Step-by-step explanation:
Answer:
90°
Step-by-step explanation:
This is a kite.
The angle measures of the diagonals (the lines in the middle) are always going to be 90° if they looks like this without any other measures. This goes for all other quadrilaterals as well.
m∠2=90°

Answer:
8.45 grams
Step-by-step explanation:
In a science experiment, Shelly has to weigh a compound in grams. The balance in her school measures in milligrams (mg). Shelly finds that the weight of the compound is 8,450 mg. What is the value in grams (g) that Shelly should enter?
1 mg = 0.001 g
8450 mg = x
Cross Multiply
= 8450 × 0.001 g
= 8.45 g
Therefore, Shelly should enter 8.45 grams

Answer: x^3+5x^2
Step-by-step explanation:
Sketch the graph of the following equations: y=x+5, y=-(x+5), and y = |x+5|
The graph of functions y=x+5, y=-(x+5), and y = |x+5| are shown in figure.
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Equations are,
y = x + 5
y = - (x + 5)
y = |x + 5|
Since, All equations shows equation of line.
Hence, We can draw all the equations as shown in figure.
y = x + 5
Slope = 1
y - intercept = 5
y = - x - 5
Slope = - 1
y - intercept = - 5
Thus, The graph of functions y=x+5, y=-(x+5), and y = |x+5| are shown in figure.
