Answer:
∝ = 60.50°
Step-by-step explanation:
![AC = \sqrt{AB^{2} + BC^{2} } = \sqrt{128} \\\\AM = \frac{AC}{2} = \frac{\sqrt{128} }{2} \\\\](https://tex.z-dn.net/?f=AC%20%3D%20%5Csqrt%7BAB%5E%7B2%7D%20%2B%20BC%5E%7B2%7D%20%7D%20%3D%20%5Csqrt%7B128%7D%20%5C%5C%5C%5CAM%20%3D%20%5Cfrac%7BAC%7D%7B2%7D%20%3D%20%5Cfrac%7B%5Csqrt%7B128%7D%20%7D%7B2%7D%20%5C%5C%5C%5C)
∡VAM = ∝
![tg \alpha = \frac{VM}{AM} = \frac{10}{\frac{\sqrt{128} }{2} } = 1.76776695297 \\\\](https://tex.z-dn.net/?f=tg%20%5Calpha%20%3D%20%5Cfrac%7BVM%7D%7BAM%7D%20%3D%20%5Cfrac%7B10%7D%7B%5Cfrac%7B%5Csqrt%7B128%7D%20%7D%7B2%7D%20%7D%20%3D%201.76776695297%20%5C%5C%5C%5C)
![\alpha = arctan (1.76776695297) = 60.50](https://tex.z-dn.net/?f=%5Calpha%20%3D%20arctan%20%281.76776695297%29%20%3D%2060.50)
Well we can just add the 35% instead of subtracting to figure it out.
35%+91= 122.85.
So the original price is $122.85
Hope this explanation helps!
