Answer 1

Hello, the correct answer to your question should be 5.

As seen in the photo below, the sum of the given angle values must equal
`180^o`.

• 
  `(17x-5)+(21x-5)=180`

Therefore, when we add these two values, we get the number
. If we equalize this number to
`180^o`, we find the value of our
`x` as
`5`.

1. 
   `38x-5=180`
2. 
   `38x=190`
3. 
   `x=5`
