State whether or not each of the triangles are similar (use either AA, SSS, or SAS)
Answer:
ΔABC and HGF are similar.
Step-by-step explanation:
In the given triangles ABC and HGF,
If both the triangles are similar,
Their corresponding sides will be proportional.
[tex]\frac{AB}{GH}=\frac{BC}{FG}= \frac{AB}{HF}[/tex]
[tex]\frac{72}{12}=\frac{48}{8}= \frac{84}{14}[/tex]
6 = 6 = 6
True.
Therefore, ΔABC and HGF are similar.
Need help with this trigonometry word problem
The angle of elevation of the top of the building at a distance of 50 m from its foot on a horizontal plane is found to be 60°. Find the height of the building.
Please show your work
Answer:
[tex] \huge \boxed{ \boxed{ 50 \sqrt{3} \: or \: 86.6}}[/tex]
Step-by-step explanation:
to understand thisyou need to know about:trigonometryPEMDASlet's solve:to find the height we need to use tan function because we are given adjacent and angle and we need to figure out opposite (height) [tex]\tan(\theta)=\dfrac{opposite}{adjacent}[/tex]
let opposite be AC
let adjacent be BC
according to the question:
[tex] \quad \: \tan( {60}^{ \circ} ) = \dfrac{AC}{BC} [/tex]
now we need a little bit algebra to figure out AC (height)
[tex] \sf \: substitute \: the \: given\: value \: of \: BC : \\ \tan( {60}^{ \circ} ) = \frac{AC}{50} [/tex][tex] \sf sustitute \: the \: value \: of \: \tan( {60}^{ \circ} ) \: i.e \: \sqrt{3} : \\ \sqrt{3 } = \frac{AC }{50} [/tex][tex] \sf cross \: multiplication: \\ 50 \sqrt{3} = AC[/tex][tex] \sf swap \: sides \: (your \: wil) : \\ AC = 50 \sqrt{3} \\AC = 86.6 \: ( \sf \: decimal \: if\: needed)[/tex][tex]\text{we are done!}[/tex]

Answer:
She made $1230 more on printed shirts than plain shirts in 25 weeks.
Step-by-step explanation:
Hi,
Okay, I have to admit, this is pretty complicated. But, it's not impossible :) First things first, we know that the equation in the table is the number of shirts sold after W number of weeks. We know that we need to, first, find the total number of shirts sold in 25 weeks.
The equation for the plain shirts is 5w -4. Let's start with that.
Plugin 25 for w to find the total number of plain shirts sold after 25 weeks.
5w - 4
5(25) - 4
= 121
She sold 121 plain shirts after 25 weeks. But we're not done yet, we still have to see how much money she made after selling 121 plain shirts. To do this, we have to multiply the total number of plains shirts sold by 15. (we know that each plain short costs $15, that's why we're multiplying it by 121)
When you do this...
121 x 15
You get...
$1815
She got $1815 after 25 weeks just for selling plain shirts.
Now, let's find the total cost of printed shirts after 25 weeks.
The equation for the printed shirts if 8w + 3.
8w + 3
8(25) + 3
= 203
She sold 203 printed shirts in 25 weeks. Let's find the cost. Each printed shirt costs $15 so we need to multiply 203 by 15.
203 x 15
You get...
$3045
She made $3045 by selling printed shirts in 25 weeks.
Now, we have to subtract $3045 by $1815 to find how much more she made. You get...
3045 - 1815
= $1230
She made $1230 more on printed shirts than plain shirts in 25 weeks.
I really hope this helps :)

Wesley's laundry basket has a rectangular base with an area of 200 square inches. The basket has a height of 24 inches and it is full of clothes. What is the volume of Wesley's laundry basket?
Answer:
4800 cubic Inches
Step-by-step explanation:
Wesley's laundry basket has a rectangular base with an area of 200 square inches. The basket has a height of 24 inches and it is full of clothes. What is the volume of Wesley's laundry basket?
The volume of Wesley's Rectangular laundry basket = Area of the Base × Height of the basket
Base area = 200 square inches
Height of the basket = 24 inches
Volume of the basket = 200 square inches × 24 inches
= 4800 cubic Inches

PLZ HELP GIVING ALL MY POINTS VERY URGENT
Answer:
88ft²
Step-by-step explanation:
Hey There
So first we want to find the area of the square
to do that we do 8x8 which equals 64
then we want to find the area of the triangle
to do so we multiply the base (8) and the height and divide that by 2
8x6=48
48/2=24
then we add the two together
24+64=88
88ft² is your answer :)
