ANSWER
5.5
EXPLANATION
We can use the cosine rule to find the missing side length.
The cosine rule is given as;
![{a}^{2} = {b}^{2} + {c}^{2} - 2bc \cos( A)](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20%20%3D%20%20%7Bb%7D%5E%7B2%7D%20%20%2B%20%20%7Bc%7D%5E%7B2%7D%20%20-%202bc%20%5Ccos%28%20A%29%20)
Let the missing side be "a".
Then,
![{a}^{2} = {9}^{2} + {6}^{2} - 2 \times 9 \times 6 \cos(37 \degree)](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20%20%3D%20%20%7B9%7D%5E%7B2%7D%20%20%2B%20%20%7B6%7D%5E%7B2%7D%20%20-%202%20%5Ctimes%209%20%5Ctimes%206%20%5Ccos%2837%20%5Cdegree%29%20)
![{a}^{2} = 81+ 36- 86.253](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20%20%3D%20%2081%2B%20%2036-%2086.253)
![{a}^{2} = 30.74736](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20%20%3D%20%2030.74736)
![a = \sqrt{30.747}](https://tex.z-dn.net/?f=a%20%3D%20%20%5Csqrt%7B30.747%7D%20)
![a \approx5.5](https://tex.z-dn.net/?f=a%20%5Capprox5.5)
Therefore the missing side length is approximately 5.5 units to the nearest tenth.
Answer:
approximately 12.04 units
Step-by-step explanation:
We'll use the Pythagorean Theorem to solve this problem.
There are two points here. The horizontal distance between them is 8 units and the vertical distance is 9.
According to the Pythagorean Theorem (or the Distance Formula), the distance between the two points is
d = √(8^2 + 9^2) = √(64 + 81) = √145 units, or approximately 12.04 units.
Answer: Nevertheless, the theorem came to be credited to Pythagoras. It is also proposition number 47 from Book I of Euclid's Elements. According to the Syrian historian Iamblichus (c. 250–330 ce), Pythagoras was introduced to mathematics by Thales of Miletus and his pupil Anaximander.
