Answer:

4. -11

5. -7

Step-by-step explanation:

So a triangle has a total of 180 degrees.

Looking at number 4 first, add up what we know and we have 191 degrees. This is higher than 180 degrees so we know x is negative. 180-191 = -11.

Therefore, x = -11

We do the same thing for 5 to get x = -7
