It is an isosceles triangle which means two sides are the same and when two sides are the same then the two angles are the same. The bottom one is
80 degrees so the other angle equals to 80 degrees
Add both 80 degrees angle
80+80= 160 In a triangle all the angles equal to 180, so now you subtract
180-160 = 20
The angles are 80, 80 ,20
The 20 is on top and the two 80 are on the bottom

Given two points, say points
A and
B, we can use the slope formula to find the slop of the line:
![\frac{y_{2} - y_{1}}{x_{2} - x_{1}}](https://tex.z-dn.net/?f=%20%5Cfrac%7By_%7B2%7D%20-%20y_%7B1%7D%7D%7Bx_%7B2%7D%20-%20x_%7B1%7D%7D%20)
If
A has coordinates of
(w,c) and
B has coordinates of
(y,z), we can find the slope.
![\frac{z-c[tex]y-w= \frac{z-x}{y-w} (x-c)](https://tex.z-dn.net/?f=%20%5Cfrac%7Bz-c%5Btex%5Dy-w%3D%20%5Cfrac%7Bz-x%7D%7By-w%7D%20%28x-c%29)
}{y-w} [/tex]
Now we can say that we can use the point slope form formula:
![y-y_{1}=m(x-x_{1})](https://tex.z-dn.net/?f=y-y_%7B1%7D%3Dm%28x-x_%7B1%7D%29)
Now we can substitute
m for the slope, and use any points to plug in
![x_{1}](https://tex.z-dn.net/?f=x_%7B1%7D)
and
![y_{1}](https://tex.z-dn.net/?f=y_%7B1%7D)
.
Hope this helps! :^)
Answer:
Final Price = $385.60
You save = $96.40
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 482 × 20/100
Discount = 482 x 0.2
You save = $96.40
Final Price = Original Price - Discount
Final Price = 482 - 96.4
Final Price = $385.60
I’m assuming we are considering ‘before Plan A becomes cheaper’
let n be the number of times you go to the park. Plan A’s cost doesn’t depend on how many times you enter the park,
18.95 + 6.50n > 54.75
6.50n > 54.75 - 18.95
6.50n > 35.8
n > 35.8/6.50 ~ 5.508
You obviously can’t ‘half visit’ a place. So we either round up or down to the nearest whole number.
But wording here is important.
‘before’ basically implies, in this context, ‘what is the limit until x’.
Imagine the meme ‘so the limit is 412 chicken nuggets’ when some guy was paralysed after eating 413 = 412 + 1 nuggets
Using the same logic, ‘the limit is’:
n = 5 visits (round down to the nearest whole)
