Answer:
45° + x° = 90°
Step-by-step explanation:
Two angles are complementary if the sum of the angles is equal to 90 degrees. we can also said that if we had two angles A and B and these angles are complementary, the equation that represent this situation is:
A + B = 90°
Then, if a 45°angle is complementary to an angle measures ×°, the equation that represents this situation is:
45° + x° = 90°
Therefore, solving for x°, we get:
45° + x° - 45° = 90° - 45°
x° = 45°
it means that a 45°angle is complementary to an angle measures 45°
Step-by-step explanation:
5.|12 - r| > 15
|12 - r| > 15/5
|12 - r| > 3
12 - r < -3 or 12 - r > 3
-r < -3 - 12 or -r > 3 - 12
-r < -15 or -r > -9
r > 15 or r < 9
