Find the area of the
regular figure below:
A) 414.5 ft2
B) 421.3 ft2
C) 425.1 ft2
D) 432.9 ft2
E) 443.4 ft2
pls show work
Answer:
E. 443.4 ft²
Step-by-step explanation:
Since it is a regular triangle, it means all three sides are of equal lengths and all angles are of the same degree measure.
Therefore, all sides = 32 ft each
Each equal angle = 60° (sum of all angles = 180)
The area of the triangle can be calculated using the formula, ½*a*b*sin(C),
Where,
a = 32 ft
b = 32 ft
C = 60°
Plug in the values
Area = ½*32*32*Sin(60)
Area = 443.4 ft² (nearest tenth)

select the correct trigonometric ratios for angle 0
Answer:
A, D, and F
Step-by-step explanation:
First off, we're not given the hypotenuse's length, so let's use the Pythagorean Theorem to find it:
[tex]1^2+3^2=c^2\\1+9=c^2\\10=c^2\\c=\sqrt{10}[/tex]
With that, we can refer to SOH-CAH-TOA to help us find sine, cosine, and tangent:
SOH (Sine = Opposite/Hypotenuse)
[tex]\sin{\theta}=1/\sqrt{10}=\sqrt{10}/10[/tex]
CAH (Cosine = Adjacent/Hypotenuse)
[tex]\cos{\theta}=3/\sqrt{10}=3\sqrt{10}/10[/tex]
TOA (Tangent = Opposite/Adjacent)
[tex]\tan{\theta}=1/3[/tex]
From this, we can see that A matches up with sine, and we can eliminate B and C.
Cosecant, secant, and cotangent are all reciprocals of the three basic trig ratios:
[tex]\csc{\theta}=1/\sin{\theta}=\sqrt{10}\\\sec{\theta}=1/\cos{\theta}=\sqrt{10}/3\\\cot{\theta}=1/\tan{\theta}=3[/tex]
D matches with cosecant, and F matches with cotangent, so the correct trig rations for θ are A, D, and F.

can someone please do the 2a 2b 2c 2d 2e and 2f ill mark u brainlist
Answer:
2a: 5
2b: 7
2c: 10
2d: 2
2e: 3
2f: 2
Step-by-step explanation:
To solve all of these you just get the variable (x) by itself
2A: 9x-41=39-7x
Add 7x from both sides and then add 41 to get
16x=80
Divide by 16 and get x=5
2B: 3x-13=50-6x It's the same process as before for this question
Add 6x and 13 to both sides to get
9x=63
divide by 9 and get x=7
2C: 5x-17=83-5x
Add 5x and 17 to both sides
10x=100
divide by 10
x=10
2d: 13x-16=24-7x
Add 7x and 16 to both sides to get
20x=40
divide by 20 and get x=2
2e: 12x-13=53-10x
Add 10x and 13 to both sides to get
22x=66
divide by 22 and get x=3
2f: 17x-21=51-19x
Add 19x and 21 to both sides and get
36x=72
divide by 36 and get x=2
solve for x and y please help
Answer:
y = 48, x = 11
Step-by-step explanation:
6x = 3x + 33
3x = 33
x = 11
6x + 3x + 33 + y = 180
66 + 33 + 33 + y = 180
66 + 66 + y = 180
132 + y = 180
y = 180 - 132
y = 48

Alicia is writing the program for a video game.
For one part of the game, she uses the rule
(x,y)→(x−7,y+2)
to move points on the screen.
What output does the rule give when the input is
(−4,−6)
? Show your work.
What output does the rule give when the input is
(2,−9)
? Show your work.
Answer:
(-11,-4) and (-5,-7)
Step-by-step explanation:
the rule (x,y)→(x−7,y+2) means the x-value of the coordinate decreases by 7, and the y-value of the coordinate increases by two.
Apply the rule to the 1st question by plugging in the coordinates:
(x,y)→(x−7,y+2)
(−4,−6)→((-4)−7,(-6)+2)
(−4,−6)→(-11,-4)
Let's use the same process for the 2nd question:
(x,y)→(x−7,y+2)
(2,−9)→((2)−7,(-9)+2)
(2,−9)→(-5,-7)
30 points!

Answer:
a)60°
b)BD=10
c)AB=20
d)100√3
Step-by-step explanation:
B
let's BD be x
according to the question
[tex] \tan( {30}^{o} ) = \frac{x}{10 \sqrt{3} } [/tex]
[tex] \frac{ \sqrt{3} }{3} = \frac{x}{10 \sqrt{3} } [/tex]
[tex]3x = 10 \sqrt{3} \times \sqrt{3} [/tex]
[tex]3x = 30[/tex]
[tex]x = 10[/tex]
thereforeBD=10c)
according to Pythagoras theorem
a²+b²=c²
c=√a²+b²
c=√10²+(10√3)²
c=√100+300
c=√400
c=20
D)
the two triangles are congruent
so AC=2(10√3)
=20√3
as we know
area of a triangle =
½bh
=½×20√3×10
=10√3×10
=100√3
this will guide youWhat is the range of possible sizes for side x? the other two sides are 8.0 and 8.5
Answer: 0.5 < x < 16.5.
Step-by-step explanation:
Given: Two sides of triangle: 8.0 units and 8.5 units
Measure of third side = x
According to the triangle's inequality,
Sum of any two sides > third side. (i)Difference between the sides < third side. (ii)If x is the third side, then
x < 8+8.5 [Using (i)]
i.e. x< 16.5
Also, x > 8.5-8 [Using (ii)]
i.e. x> 0.5
Hence, Range of possible sizes for side x would be 0.5 < x < 16.5.
Answer:
0.5, 16.5

3. A technician worked 45 hours in one week He gets paid double for every hour over 40 hours that he works. If his regular wage is $825 per hour, approximately how much overtime pay should he receive plz explain
Answer: 41,250$ (I think)
Step-by-step explanation:
1 hour —> 825$
40 hours —> 825$ x 40 = 33,000$
The after the 40 hours he gets paid x2 and he works for 5 hours
1 hour —> 825$ x 2 = 1,650$
5 hours —> 1650$ x 5 = 8,250$
33,000 + 8,250 = 41,250$
The longest length side of an acute isosceles triangles is 12 centimeters. Rounded to the nearest tenth, what is the smallest possible length of one of the two congruent sides
Answer:
8.5
Step-by-step explanation:
Given that;
The longest side of an acute isosceles triangle = 12 centimeters
Since the two remaining sides are congruent, then they both have the same length ;
Let the length of the two remaining sides = 2x,
The length of each side :
Length of longest side / sqrt(2)
x = 12 /sqrt(2)
x = 12 / 1.4142135
x =8.4852813
x = 8.5
