Answer:
x = 4.8
Explanation:
With angles like this these ones, the 2 lines equal the same amount. To find the length of one of the lines, you multiply the given lengths.
So, for the first angle, the line with both angles has a 4 and 6, so the length of the line is 24.
Since the lines are equal, to find the length of x you take 24 and divide it by 5, which gives you 4.8, or 24/5.
This means x = 4.8.
To double check, you can simply multiply 4 and 6, then 5 and 4.8. If the answers are the same, it is correct.
This applies to all 3 angles shown.
Hope this helps!
