Answer:
-7?
Step-by-step explanation:
I mean, is the question 20 - 27 =? Or it's something else? Lol.
20 - 27 = -7, it's very straightforward cannot write it in more detailed way. When we substract a number from another and the first one is smaller the result is a negative number. Imagine someone sells up to 3 apples, you ask him to give you 5. He gives you all 3 of his so he has 0 but you force him to go and get another 2 for you. He lost another 2, so he has less than 0 now. He has -2 apples: 3 - 5 = -2.
Now, I don't know if this is the question or these are set of exercises you must solve and your picture just didn't upload. Let me know if you need help with anything else.
The exact area of triangle ABC is 93.51 cm².
The given parameters;
- <em>Height of the triangle, h = 18 cm</em>
The base of the triangle is calculated by using trigonometry ratio as follows;
![tan (30) = \frac{b}{18} \\\\](https://tex.z-dn.net/?f=tan%20%2830%29%20%3D%20%5Cfrac%7Bb%7D%7B18%7D%20%5C%5C%5C%5C)
where;
- <em>b </em><em>is the </em><em>base </em><em>of the </em><em>triangle ABC</em>
<em></em>
<em></em>
<em></em>
The area of the triangle ABC with the calculated base and given height is calculated as follows;
![A = \frac{1}{2} \times base \times height\\\\A = \frac{1}{2} \times 10.39 \times 18\\\\A = 93.51 \ cm^2](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%20base%20%5Ctimes%20height%5C%5C%5C%5CA%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%2010.39%20%5Ctimes%2018%5C%5C%5C%5CA%20%3D%2093.51%20%5C%20cm%5E2)
Thus, the exact area of triangle ABC is 93.51 cm².

Each book costs $15. since he had 18 dollars left, you can subtract 18 from 108. then divide that answer by 6. 90/6 = 15.
Hope that helped!
