Answer:
PICTURE?
Step-by-step explanation:
First you need to find the common denominator. both 6 and 7 go in to 42 evenly
multiply 5/6 by 7 to get 35/42
multiply 2/7 by 6 to get 12/42
subtract 12 from 35 to get 23
23/42

The question is related to trigonometry and we have to use the formula of double angle .
Here we use double angle formula of tangent function which is
![tan(2x) = \frac{2tan(x)}{1-tan^2(x)}](https://tex.z-dn.net/?f=%20%20tan%282x%29%20%3D%20%5Cfrac%7B2tan%28x%29%7D%7B1-tan%5E2%28x%29%7D%20%20%20)
Given expression is
![\frac{2tan (5 \degree)}{1-tan^2(5 \degree)}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2tan%20%285%20%5Cdegree%29%7D%7B1-tan%5E2%285%20%5Cdegree%29%7D%20%20%20)
Comparing it with double angle formula, we will get x = 5
SO the required expression is equal to
![\frac{2tan (5 \degree)}{1-tan^2(5 \degree)} =tan(2*5 )](https://tex.z-dn.net/?f=%20%20%5Cfrac%7B2tan%20%285%20%5Cdegree%29%7D%7B1-tan%5E2%285%20%5Cdegree%29%7D%20%20%3Dtan%282%2A5%20%29%20)
![\frac{2tan (5 \degree)}{1-tan^2(5 \degree)} =tan(10 )](https://tex.z-dn.net/?f=%20%5Cfrac%7B2tan%20%285%20%5Cdegree%29%7D%7B1-tan%5E2%285%20%5Cdegree%29%7D%20%20%3Dtan%2810%20%29%20)
So the answer is tan(10) .
