Slope is the change in Y over the change in. X
Using two of the given points:
Slope = 70-45 / 25-10
Slope= 25/ 15
Slope = 5/3
Solving the triangle requires solving all of the dimensions involve in the polygon given. We are given an angle, and two of the sides of the triangle. We can solve the third side by using the law of cosines.
b² = a²+c²-2accos(B)
b² = 38² + 18² - 2(38)(18)cos(36)
b = 25.7
We use the law of sines to solve for the angles.
a/sinA = b/sinB
38/sinA = 25.7/sin36
A = 60.4°
C = 180 - 36 - 60.4 = 83.6°
(y2-y1)/(x2-x1)
=(0-1.5)/(-2-0)
=0.5
The correct answer according to my brain is 1/7
If you have an iPhone which I do you can use it’s provided calculator ...I added 11.00 and 5.56 together and I ended up with 16.56 and there’s a % button on it and it does calculations for you.. so I added 7% to the order and it spit out $1.59 then I pressed add and it gave me $17.71 subtract 20.00-17.71 you get $2.29 which is your answer
