Answer:
2:3=14:21
Step-by-step explanation:
2+2=5
35/5=7
7*2=14
7*3=21
Answer/Step-by-step explanation:
a. Unknown side, b, using the Pythagorean theorem is solved as shown below.
![b^2 = c^2 - a^2](https://tex.z-dn.net/?f=%20b%5E2%20%3D%20c%5E2%20-%20a%5E2%20)
![b^2 = 45^2 - 27^2](https://tex.z-dn.net/?f=%20b%5E2%20%3D%2045%5E2%20-%2027%5E2%20)
![b^2 = 1,296](https://tex.z-dn.net/?f=%20b%5E2%20%3D%201%2C296%20)
![b = \sqrt{1,296}](https://tex.z-dn.net/?f=b%20%3D%20%5Csqrt%7B1%2C296%7D)
![b = 36](https://tex.z-dn.net/?f=%20b%20%3D%2036%20)
Unknown side, b, = 36 km
b. Perimeter of the triangle = sum of all the sides of the ∆ = ![36 + 45 + 27](https://tex.z-dn.net/?f=%2036%20%2B%2045%20%2B%2027%20)
![perimeter = 108 km](https://tex.z-dn.net/?f=%20perimeter%20%3D%20108%20km%20)
c. Area of triangle = ½*base*height
where,
Base = 36 km
Height = 27 km
![Area = \frac{1}{2}*36*27](https://tex.z-dn.net/?f=%20Area%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2A36%2A27%20)
![Area = 18*27](https://tex.z-dn.net/?f=%20Area%20%3D%2018%2A27%20)
![Area = 486 km^2](https://tex.z-dn.net/?f=%20Area%20%3D%20486%20km%5E2%20)
So I think it’s 6:2 bc 6 apples and two oranges make 8 so the 8 pieces of fruit are the apples and oranges meaning that it probably put that to throw you off
