What is the length of YX?
Answer:
hi
Step-by-step explanation:
hi
Answer:
4cm.Step-by-step explanation:
Because,
Given two triangles are similar.
Ratio of their sides...
24/8 = 4
Therefore,
Side YX is corresponding to side NM.
Therefore, 12/YX = 4
YX = 4cm.
Write an equation in point-slope form of the line that passes through the point (
3,-1)
and has a slope of -2
Answer:
Look below.
Step-by-step explanation:
Point slope fromula: y-y1=m(x-x1)
First we have to plug in our points and slope into the formula.
3 will be plugged into x1 while -1 will be plugged into y1.
Since m represents slope we will plug in -2 into m.
Answer: y+1=-2(x-3)
need help to Find the apothem.
The apothem of a polygon, in this case a, can be found using the formula
Apothem=circumradius*cos(pi/sides)
Note in this problem, its a hexagon which makes the circumradius = to the side length since a regular hexagon can be split into 6 equilateral triangles.
a=47*cos(pi/6)=40.7 (approximation)
Hope it helped!

a) BCD is a straight line.
Triangle ABC is equilateral.
CE = DE
E
Not drawn
accurately
А
320
B
С
Work out the size of angle x.
(4)
Answer:
x = 46°
Step-by-step explanation:
Since Δ ABC is equilateral then interior angles = 60°
Since CE = DE then Δ CDE is isosceles and the base angles are congruent, so
∠ ECD = [tex]\frac{180-32}{2}[/tex] = [tex]\frac{148}{2}[/tex] = 74°
BCD is a straight line, then the 3 angles on it sum to 180°, that is
60° + 74° + x = 180°
134° + x = 180° ( subtract 134° from both sides )
x = 46°
Gianna's family reserved a campsite for 5 nights for a family vacation. They paid $115 total for the reservation. Let c be the cost of the reservation per night. Write and solve an equation to find c.
Answer:
23$
Step-by-step explanation:
they slept there 5 nights, and paid 115 all together so you divide 115 by 5 to get the total cost for just one night, which is 23 dollars

Find the area. The figure is not drawn to scale. Hint: Find the sum of the areas of 2 triangles and 2 parallelograms.
Select one:
a. 188 in.2
b. 278 in.2
c. 322 in.2
d. none of these
Answer:
d. None of the above
Step-by-step explanation:
✔️Area of triangle 1 = ½*b*h
b = 11 in.
h = 3 in.
Area of triangle 1 = ½*11*3 = 16.5 in.²
✔️Area of triangle 2 = ½*b*h
b = 8
h = 9
Area of triangle 2 = ½*8*9 = 36 in²
✔️Area of parallelogram 1 = b*h
b = 11 in.
h = 9 in.
Area of parallelogram 1 = 11*9 = 99 in.²
✔️Area of parallelogram 1 = b*h
b = 9 in.
h = 11 in.
Area of parallelogram 2 = 9*11 = 99 in.²
✅Total area = 16.5 + 36 + 99 + 99 = 250.5 in.²

will mark brainliest and rate 5/5
Answer:
Option D, $2.71
Step-by-step explanation:
Step 1: Figure out the height
[tex](5.4)^{2} + b^{2} = (17.2)^{2}[/tex]
[tex]29.16 + b^{2} = 295.84[/tex]
[tex]b^{2} = 266.68[/tex]
[tex]\sqrt{b^{2}} = \sqrt{266.68}[/tex]
[tex]b = 16.33[/tex]
Step 2: Figure out the area
[tex]A = \frac{5}{4} * tan(54) * a^{2} + 5 * \frac{a}{2} * \sqrt{h^{2} + (\frac{a * tan(54)} {2})^{2}}[/tex]
[tex]A = \frac{5}{4} * tan(54) * (8)^{2} + 5 * \frac{(8)}{2} * \sqrt{(16.33)^{2} + (\frac{(8) * tan(54)} {2})^{2}}[/tex]
[tex]A = 454.77[/tex]

0. Multi-Step Nathanial has a dog walking
business. He charges $3 for every 15 minutes
of walking. How much will Nathanial charge to
walk a dog for one hour?
Answer:
Nathanial will charge $12
Step-by-step explanation:
If he charges $3 per 15 minutes, one hour is 60 minutes. And 60 divided by 15 is 4 so you do 3x4 because he charges $3 per 15 minutes.
find the exact value of x.
Answer:
9*√3
Step-by-step explanation:
The exact value of Sin60 = √3/2
Sin(60) = opposite side/ hypotenuse
hypotenuse = 18
√3/2 = x / hypotenuse
√3 / 2 = x / 18 multiply by 18
18 √3 /2 = x divide by 2
9 √3 = x

10y = 186
y= 18.6
Angle O = 3(18.6) - 6 = 49.8
Answer 49.8

Ms. Abreau is flying to Florida for the 90° Angle Conference, where the temperature s just right. Her plane is 1200 feet in the air and the runway is 3400 feet horizontally away. What is the angle of depression formed from the plane to the runway ? Round to the nearest tenth if necessary and just the number please in your answer, we know it is degrees.
Answer:
19.4 degrees
Step-by-step explanation:
Using the SOH CAH TOA trigonometry identity
Given
Height of plane from the ground= 1200 = adjacent
Horizontal distance = 3400ft = Adjacent
Required
angle of depression theta
tan theta = opp/adj
tan theta = 1200/3400
tan theta = 12/34
tan theta = 0= arccos.3529
theta= (0.3529)
theta = 19.4 degree
Hence the angle of depression is 19.4 degrees
