Answer:
x = 35°
Explanation:
Complementary angles are two angles whose measures sum to 90°.
In this case, we have one angle measuring 55°, and the other angle measuring x. Since they are complementary, we can set up the equation:
x + 55° = 90°
Now, solve for x by subtracting 55° from both sides of the equation:
x + 55° - 55° = 90° - 55°
x = 35°
Therefore, the measure of angle x is 35°.
