Step-by-step explanation:
sinA= BC/AC
= 24/26
= 12/13
cosA= AC/AB
= 10/26
= 5/13
tanA= BC/AC
=24/10
= 12/5
Answer: The total price of a bench is 1.008x.
Step-by-step explanation:
Since we have given that
Let the cost price be 'x'.
Mark up % = 120%
So, Mark up value would be
![\dfrac{120}{100}x\\\\=1.20x](https://tex.z-dn.net/?f=%5Cdfrac%7B120%7D%7B100%7Dx%5C%5C%5C%5C%3D1.20x)
Discount % = 20%
Amount of discount is given by
![\dfrac{20}{100}\times 1.2x\\\\=0.2\times 1.2x\\\\=0.24x](https://tex.z-dn.net/?f=%5Cdfrac%7B20%7D%7B100%7D%5Ctimes%201.2x%5C%5C%5C%5C%3D0.2%5Ctimes%201.2x%5C%5C%5C%5C%3D0.24x)
So, it becomes,
Amount after discount is given by
![1.2x-0.24x\\\\=0.96x](https://tex.z-dn.net/?f=1.2x-0.24x%5C%5C%5C%5C%3D0.96x)
Sales tax = 5%
Amount of sales tax would be
![\dfrac{100+5}{100}\times 0.96x\\\\=\dfrac{105}{100}\times 0.96x\\\\=1.05\times 0.96x\\\\=1.008x](https://tex.z-dn.net/?f=%5Cdfrac%7B100%2B5%7D%7B100%7D%5Ctimes%200.96x%5C%5C%5C%5C%3D%5Cdfrac%7B105%7D%7B100%7D%5Ctimes%200.96x%5C%5C%5C%5C%3D1.05%5Ctimes%200.96x%5C%5C%5C%5C%3D1.008x)
Hence, the total price of a bench is 1.008x.
Answer:
reverse it x-15=4 do 15+4=x
Step-by-step explanation:
Answer:
y = -20
Step-by-step explanation:
Move all terms not containing y to the right side of the equation.
Therefore, that is how you got your answer: y = -20
CXB = 40 degrees
I am not positive but from what I have looked up this is the answer.
