Answer:
39°
Step-by-step explanation:
At the section the angles are connected, meaning that the angle across from w is the same as w and same applied to x. To find y, you first need to find w, to find the 2nd angle of the triangle of the right.
To do this, you need to add up 42 + 85.
(All triangles angles = 180)
42+85=127
subtract this from 180 to find angle w
180 - 127 = 53
53 = Angle w, which is the same as the angle across from angle w (second angle).
Second, take 53 + 88 = 141
Subtract this from 180
180-141 = 39.
39 is y°
or
y° = 39
(2. Given that AABC is similar to ADEC, find the values of the unknowns in the figure.
7.3 cm
А Ar
B
489
8 cm
С
10 cm
60°
E
D
y cm
Answer:
x = 72 degrees
y = 9.125 cm
Step-by-step explanation:
the sum of degrees of all angles in a triangle is 180.
because the triangles are similar, all the angles must be the same in both. and the side lengths of one triangle must all have the same scaling factor compared to the other triangle.
the similarity tends is that the angle at E is the same as at B (48 degrees). so, then the angles at C are 60 degrees. that leaves for the angle at D (x) 180 - 60 - 48 = 72
BC (8) is scaled to CE (10) by the factor 10/8 = 5/4
so, y must have the same scaling factor in relation to AB (7.3)
y = 7.3 × 5/4 = 9.125

HELP!!!! if you answer you get 20 points.
Answer:
Very last choice is the answer.
Step-by-step explanation:
Remark
The thing that is most important is that the horizontal line connect h and the radius is parallel to the cut of the sphere if it was placed right in the middle. That line swings around as though the center was a pivot.
Solution
So what you have is a circle when that line goes around that part of the sphere. To find the length of that line, use the Pythagorean Theorem. Call the line r1.r1 ^2 = r^2 - h^2So the area is pi * r1^2Area = pi (r^2 - h^2)The very last one is the answer.What does x = ? Please help meee

160 m of fencing to enclose a quadrilateral shape pen (3 sided) for a children's play area. Determine the shape of the children's play area that gives the maximum area.
Answer:
A square of side length 40 m will give the maximum area of the play area
Step-by-step explanation:
Mathematically, it has been established that a square gives the maximum area of a quadrilateral
Hence, for us to have a maximum area of the given perimeter, we have to divide the perimeter by 4 to get the side length of the square
From what we have, we know that the perimeter of the fencing is 160 m
To get the side length, we divide the perimeter by 4
Side length of the shape would be 160/4 = 40 m

For the function
[tex]f(x)=x^2-2x-8\\[/tex]
Find the equation of the line of symmetry.
no links please and thank you! Please help ASAP! Will give Brainliest!
Answer:
x = 1
Step-by-step explanation:
For a quadratic function [tex]f(x)=ax^2+bx+c[/tex], the axis of symmetry is
[tex]x=-\frac{b}{2a}[/tex].
This comes from using part of the Quadratic Formula for finding zeros of the function:
[tex]x=\frac{-b \pm \sqrt{b^2-4ac}}{2a} = \frac{-b}{2a} \pm \frac{\sqrt{b^2-4ac}}{2a}[/tex]
See the -b/(2a) in the first term? That's the x-coordinate of the vertex (turning point) of the parabolic graph of the function. The axis of symmetry goes through the vertex.
Samuel spends a winter day recording the temperature once every three hours for science class. At 9 am, the temperature was -14.7°F. Between 9am and noon, the temperature increased by 17.8°F. Between noon and 3pm, the temperature increased by 5.1°F. Between 3pm and 6pm, the temperature went down 14.5°F. What was the temperature at 6pm?
Answer:
The temperature at 9 am = -14.7°F
Between 9am and 12 pm = -14.7 + 17.8 = 3.1°F
Between 12pm and 3 pm = 3.1+5.1 = 8.2°
Between 3pm and 6 pm = 8.2-14.5 = -6.3°F

PLEASE ASAP ILL GIVE BRAINLIEST.
Answer: 12 km\h north
Step-by-step explanation:
I actually have good guesses
Velocity = 12 km/h
-
Velocity can be defined as the division between distance traveled and the time it took for that distance to be traveled:
Velocity = Distance / Time
With the above information in mind, we can calculate the velocity of the bicycle:
Velocity = 18 km / 1.5 h
Velocity = 12 km/h
Thus the velocity of the bicycle is 12 kilometers per hour.
What is the area of a regular hexagon with sides that measure 10 feet and an
apothem that measures 8.66 feet?
Answer:
259.8 square feet
Step-by-step explanation:
What is the area of a regular hexagon with sides that measure 10 feet and an
apothem that measures 8.66 feet?
The formula to solve the above question is given as:
Area = (3√3 s²)/ 2 where
s is the length of a side of the regular hexagon
Area of this Hexagon is calculated as:
= (3√3 × 10²)/2
= 3√3 × 100/2
= 259.80762114 square feet
Approximately = 259.8 square feet
The area of the regular hexagon = 259.8 square feet
