X = ?

Can someone tell me
The answer to this question

Step-by-step explanation:

To find x:

We can use the angle sum property of a triangle which states that, The sum of all internal angles of a triangle is always equal to 180°.

Therefore,

Now that we know the value of we can use it to find the value of .

We can see that angle and are supplementary which means:

Now that we know the value of we can use the angle sum property of a triangle again:
