Vertical angles are equal...so set ur angles equal to each other and solve for x
5x + 10 = 7x - 12

22 = 2x
22/2 = x
11 = x <==
Answer: 56.64%
Step-by-step explanation:
Given: Previous amount of flour = 2.26 kilograms
By the end of the baking session, amount of flour = 0.98 kilograms
Decrease in amount = 2.26-0.98 = 1.28 kilograms
Percent decrese = ![\dfrac{\text{decrease in amount }}{\text{previous amount}}\times100](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctext%7Bdecrease%20in%20amount%20%7D%7D%7B%5Ctext%7Bprevious%20amount%7D%7D%5Ctimes100)
![=\dfrac{1.28}{2.26}\times100\approx56.64\%](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B1.28%7D%7B2.26%7D%5Ctimes100%5Capprox56.64%5C%25)
Hence, the percent decrease in the amount of flour = 56.64%
