Assuming this is a triangle, all three angles should add to 180º
91 + 40 + x = 180
131 + x = 180
Subtract 131 from both sides
x = 49
The measure of angle 1 is 49º

14. What, if any, is a real solution to 5x +1 +9 - 3?<br> 1<br> C<br> D. There is no real solution.
lesya692 [45]

I believe the question is:

What is the solution to 5x + 1 +9 - 3

In this case, we solve for X.

5x + 1 + 9 - 3

5x + 10 - 3

5x + 7

5x = -7

x = -7/5

Unfortunately, It is not one of the answer choices it looks like.

Maybe you should reword your question but hopefully this is correct.

If you meant to say 5x+1 + 9 < 3 --> 5x + 10 < 3 --> 5x < -7 --> x < -7/5
