The second option is correct since the number x can't be 11 or lower.
The expression says that the sum of x + 4 needs to be higher than 15 since the symbol < is there.
Your expression in words would be:
Fifteen is less than the sum of x plus four. - Maybe it makes more sense to you now.

Answer:
x=23°; θ=87°
Step-by-step explanation:
These two angles create what is known as supplementary angles, or 2 angles that add up to 180°. We know this because all horizontal lines are 180° on either side. Since we know the total value of these two angles should equate to 180°, we can set up a simple equation:
Now, using algebra, we can solve for x:
Plugging x back into the equation, we get:
Therefore, the total angle is equal to 87° and x is equal to 23°.
