Let
![x=\arctan y](https://tex.z-dn.net/?f=x%3D%5Carctan%20y)
. Then
![\tan x=y](https://tex.z-dn.net/?f=%5Ctan%20x%3Dy)
, and so as
![x\to\dfrac\pi2^-](https://tex.z-dn.net/?f=x%5Cto%5Cdfrac%5Cpi2%5E-)
, you have
![y\to+\infty](https://tex.z-dn.net/?f=y%5Cto%2B%5Cinfty)
. The limit is then equivalent to
Answer:
The cost of one taco is $0.87 and the cost of one enchilada is $1.16
Step-by-step explanation:
Let the cost of tacos be X
and cost of enchiladas be y
So, by using given data, we have following equations
3X + 2Y = 4.93 (1)
2X + 4Y = 6.38 (2)
So, first multiply 1st equation by 2 and 2nd equation by 3, then subtracting 1st equation by 2nd.
= 2 × ( 3X + 2Y = 4.93) (1)
= 3 × (2X + 4Y = 6.38) (2)
= - (6X + 4Y = 9.86) (1)
= 6X + 12y = 19.14 (2)
= 8Y = 9.28
Y = 9.28 ÷ 8 = 1.16
By putting the value of Y in equation 1, we get
3X + 2(1.16) = 4.93
3X + 2.32 = 4.93
X = 2.61 ÷ 3 = 0.87
Hence, the cost of one taco is $0.87 and the cost of one enchilada is $1.16.

Answer:
D
Step-by-step explanation:
add up all the inside angels, you'll get 122, subtract that from the total area of the triangle which is 180. you will have 58 for your missong inside triangle. the outside line makes 180 with the angel we just found, so subtract 58 from 180 and you get 122. check out Khan Academy for help.
